Electrical specifications and tolerances are based on room temperature operation ( 23°C + 2°C ). Parts have an operating temperature range of -40°C to +125°C. While the parts will continue to operate without damage over this range, they may not stay within the specified electrical tolerances during exposure to extreme temperatures.

Note : Most current ratings (I MAX) are based upon a 40°C temperature rise during continuous operation. Parts have no polarity.

Monolithic Chip Bead

Ferrite SMT Bead & Wire Assembly

Electrical specifications and tolerances are based on room temperature operation ( 23°C + 2°C ). Parts have an operating temperature range of -45°C to +125°C. While the parts will continue to operate without damage over this range, they may not stay within the specified electrical tolerances during exposure to extreme temperatures.

Visit www.LAIRDTECH.com for additional and the most up-to-date information and for other board level part families not included in this catalog. All data charts are sortable at www.lairdtech.com.

A revolutionary new SPICE model for EMI ferrite chip beads is now available from Laird Technologies. This new design aid includes the de-rating effects of DC bias currents providing much greater accuracy for better designs the first time.

Common mode chokes are the ideal components for EMI filtering of power and signal lines. These components withstand high DC currents without degradation of filtering performance that can occur with differential mode filters like small chip beads. Stable common mode chokes allow most signals to pass unaffected, yet filter the noise (EMI) from these circuits.

Switch mode power supplies are required for most advanced electronics and harmonics of the switch mode power supply can escape the power supply as EMI. Also, the power delivery circuit often creates opportunities for unintended common mode current loops to form in the end product even when using a “certified” or “regulation compliant” power supply. Installation of a common mode choke to the supply output can significantly reduce this common mode energy flow and help insure product performance and EMI regulatory compliance. Small ferrite chip beads or inductors are degraded by the power supply output. However, common mode chokes continue their high performance regardless of the high power currents that might flow or spike in the circuit.

Modern systems are frequently an interconnection of functional blocks and connections made by cables or wiring harnesses. These interconnections often present the opportunity for common mode current loops between devices that can lead to EMI regulatory failure. The addition of a common mode choke before the connector filters these common mode currents while allowing the desired signals to pass unaffected. The result is effective communication between devices, reliable product and system operation and product EMI regulatory compliance.

Most well-designed power and signal circuits present no EMI that is caused from intended currents. As an example, at 30 MHz, a pair of traces or wires 1m long, separated by 1.3 mm, requires over 20mA differential current imbalance to exceed 100mV/m radiation 3 meters away. However, unintended, unforeseen common mode currents can exceed 100mV/m radiation with only 8mA common mode current flow! Suppression of these tiny common mode currents is often crucial to assuring EMI regulatory compliance and reliable product performance.

Ferrite common mode chokes operate by acting on the magnetic fields surrounding a pair of conductors.

Common Mode and Differential Mode Explanation

Two conductors used in a standard “differential” transmission circuit create magnetic fields surrounding the conductors. These magnetic fields flow around the conductors in the directions depicted by the black arrows.

Likewise, common mode currents generate magnetic fields surrounding the conductors. The red arrows depict the common-mode current path and the associated flux paths around the wires.

The same two wires shown above have been fitted with two seperate ferrite EMI cores in a differential-mode configuration with one core per line. In this application, each core must contain the total magnetic flux resulting from both the differential mode (intended) current and the common mode (unintended) current. In this case, the performance of the ferrite core is significantly altered by the intended current. Differential mode filters (like small chip beads) are not stable under significant load.

The same two wires have now been fitted with a ferrite EMI core in a common-mode configuration; a single core with both lines through a common opening in the core. The differential mode (black) fields in the core are now equal and opposite, which yields a net flux seen by the core of approximately zero. Saturation is no longer an issue, and a much smaller ferrite core / choke can be used. The field from the common-mode noise (red arrows) is additive and is the only remaining flux to be influenced by the core. The common mode choke configuration applies to both cable cores and board level components. Common Mode Chokes are stable under load.

Black arrows represent differential (normal) mode. Red arrows represent common mode.


Open-Mode Impedance Measurement - The open-mode impedance characterizes the impedance of only a single conductor in the ferrite common mode choke.

Normal (Differential) Mode Impedance Measurement - The normal mode impedance characterizes the impedance presented by the common mode choke to the normal (differential) signals present in the circuit. The test circuit represents the forward and return paths through the device.

Common Mode Impedance Measurement - The common mode impedance characterizes the impedance presented by the choke to the unintended common mode currents that might flow in the circuit and cause EMI failures. Since this current flows in both conductors, it is necessary to short the conductors on each side of the choke so that test current flows equally through both conductors.

Up To 75 Amps Continuous Operation Capability• Compact Design•

The Series 41 Common Mode Arrays filter common mode EMI in applications of up to 75 amps continuous operating current. The combination of very low DCR and small package size allows this choke to be used when high current and high temperature limits other common mode chokes. Additionally, the high resistivity of this ferrite material and robust product design, limits concerns about product placement experienced with conventional wire wound toroidal chokes. All versions are lead-free and RoHS compliant. Stable performance under load.

Equivalent Circuits

Dashed lines represent optional conductive traces in PC board.

Multi-choke arrays can be electrically connected in the PC board to increase effective impedance. When the PCB circuits are configured, as shown above, such that individual side-by-side chokes within one array part are connected in series, the impedance is increased by a factor of the number of passes through the part. Since internal construction of Laird Technologies ferrite common mode chokes varies, Laird Technologies refers to this special installation configuration using the different terms of “pass” (additive) or “turn” (multiplicative).

When the term “pass” is used to describe series connections through a choke, each additional pass increases the impedance (Z) in proportion to the number of series PCB connections applied. Each additional “pass” adds a choke in series. If needed, it’s an optional effective method of increasing impedance with an array.

When the term “turn” is used to describe series connection through a choke, each additional turn increases the impedance in proportion to the square of the number of series PCB connections applied. Each turn multiplies impedance.

Surface Mount Power Inductor

The DI2220V301R-10 is a surface mount, high current power inductor (in the industry’s smallest package) with exceptional performance under DC Bias. Very low DCR provides superior thermal performance under DC bias. This compact, monolithic component produces flat inductance over the driven current range (from 3 to 8 amps) comparable to a larger, heavier, wire-wound toroidal inductor. Stable performance.

Features:Low Profile (height is 3.61mm / 0.142”) • EMI resistant, fully shielded printed coil • Small footprint (one fourth the footprint of an equivalent performance, old style, wire wound inductor assembly) • Superior performance under DC Bias • Rugged, vibration resistant monolithic construction • Maximum performance at 8 amps will yield > 250nH • Distributed power multiphase DC-DC converters that use this new power inductor can operate faster, cooler and cleaner • New high performance, multiphase designs (with the new power inductor) require significantly less total pc board space and usually have lower system cost

Applications:• Power inductor for DC-DC Converter • Specifically tuned to work with the new generation of high frequency multiphase DC-DC converters • Mounting can be on back side of pc boards • Applications with Voltage Regulator Modules • Power supply bricks

Ferrite EMI Disks and Plates

These Ferrite Disks and Plates provide a simple, cost-effective solution for radiated and inductively-coupled electromagnetic interference. After the PC board soldering process, a ferrite disk or plate can be installed directly on the source of EMI (such as active devices or unwanted antennas).

Features:• Easy installation • Each part for volume production is provided with permanent, double sided 3,5 mil acrylic adhesive with 218 oz./inch2 adhesion. • Samples and sample kits are available with removable and reusable adhesive for "trial and error" testing • Variety of sizes offered • Custom parts also available.

Applications:• Ferrite disks and plates can be utilized either as inductively-coupled components or EMI shields on PC board components and traces. (Inductive coupling occurs when the ferrite affects the conducted wave form leaving the active component. The rise time of the wave form is effectively slowed by the ferrite, and the overshoot and associated ringing are attenuated. EMI shielding occurs when the ferrite absorbs the radiated emissions from active components, effectively protecting other boards or components in the vicinity from radiated contamination). • Can be used to locate unwanted EMI antennas. • Flat Flex & Ribbon cables. • Can also provide retrofit, auxiliary EMI attenuation.

Example Application Graph Explanation:The zero line on the graph represents the base line noise recorded for an unprotected microprocessor. The curve (dB down) represent the performance of the Steward ferrite plate relative to the baseline. The addition of the ferrite plates to the top of the processor in this specific application exhibits up to a 5 dB EMI reduction relative to the unprotected part. Performance can vary with different sizes, materials, processors and applications.
