13. Using note for LTCC Quadrifilar

I. Be careful when transporting A. Excessive stress or shock may make products broken or cracked due to the nature of

ceramics structure. B. The products cracked or damaged on terminals may have their property changed.

II. Be careful during storage A. Store the products in the temperature of -55 ~ 125℃ B. Keep the humidity at 45 ~ 75% around the products. C. Prevent corrosive gas (Cl2, NH3, SOX, NOX, etc.) from contacting the products. D. It is recommended to use the products within 6 months of receipt. If the period exceeds

6 months, solderability may need to be verified.

III. Be careful when soldering A. All the ground terminals, IN and OUT pad of Quadrifilar should be soldered on the

ground plane of the PCB. B. Products may be cracked or broken by uneven forces from a claw or suction device. C. Mechanical stress by any other devices may damage products when positioning them on

PCB. D. A dropped product is recommended not to be used. E. Soldering must be carried out by the condition of specification sheet. F. Any couplers which are de-soldered from PCB should not be used again.
