Resistors & Components calculators

Colour codes, component codes, power ratings and standard-value selection for real parts.

Decode 4, 5 and 6-band resistors, or enter a value to see its bands. Tolerance range and temperature coefficient included.

Decode ceramic capacitor markings — 104 is 100 nF, not 104 of anything — or work backwards from a value to the printed code.
