Resistors
Restrict the current flow Resistance value – measured in Ohms (W) Power rating – measured in Watts Types
Through hole SMD Variable (pots)
Material Carbon Wire wound Metal film
Resistor Value
0 - Black 1 – Brown 2 – Red 3 – Orange 4 – Yellow 5 – Green 6 – Blue 7 – Purple 8 –Grey 9 – White Silver = 10% Gold = 5 %
Capacitors
Store electrical energy Charges up / discharges
Takes time
Capacitors
multilayer ceramic, ceramic disc, multilayer polyester film, tubular ceramic, polystyrene, metalized polyester film, aluminum electrolytic
Capacitors
Values - Farads Actually micro-farads for electrolytic Pico-farads for other types
XYZ = XY * 10z pF J = 5% K = 10% M = 20%
Capacitors
Electrolytic capacitors Have a + side and a – side Must wire up the right way around
Inductors
Store magnetic energy
A wire winding Measured in
Henries (H) Normally mH
Core Air Iron
