Polyester Film Capacitors

Polyester (Mylar) film capacitors from 1.5nF to 1µF, 100V to 630V, sorted by value. Read the code like a ceramic: 473J = 47 × 10³ pF = 47nF, and the letter is the tolerance (J = ±5%). Stable and non-polarised, for audio, timing, snubber and mains-side circuits.

First two digits 10, then 4 zeros: 10 0000 pF.

The first two digits are the value and the third is how many zeros to add, in picofarads (pF). A letter after the number is the tolerance (J ±5%, K ±10%, M ±20%). On film capacitors a code like 2A or 2J in front is the voltage. Electrolytic capacitors print the value directly (for example 100µF 25V) and the stripe marks the negative leg.
