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
