Capacitor Code Calculator

Capacitor Code Calculator allows you to determine capacitance by the capacitor markings found on the device and to determine capacitor markings by capacitance. It displays rated capacitance, capacitor tolerance and voltage.

This tool supports 2- / 3- / 4-digit code and alphabetical code.

The 2-digit code simply defines the value in pF.

The first two numbers in 3-digit code indicate the significant digits, and the third is the multiplier — the number of zeros (ex.: code "103" indicates 10000pF). Note: in most cases the third digit (multiplier) indicates the number of zeros, but "8" is used for 0.01 and "9" is used for 0.1 multiplier. Please refer to manufacturer specifications.

In 2-digit code the letters "R", "P", "p" are used to indicate the position of a decimal point and capacitance unit — pF (ex.: code "1p5" indicate 1.5pF). The letters "N" or "n" are used to indicate the position of a decimal point and capacitance unit — nF. The letters "m" or "µ" are used to indicate the position of a decimal point and capacitance unit — µF. Two capital letters at the end of the 2-digit code represent capacitor tolerance and temperature coefficient of capacitance (ex.: code "33pKL" indicates 33pF, ±10% tolerance ("K"), -75 ppm/°C ("L")).

If 4-digit code starts with a capital letter (except "R", "P", "N"), it represents the maximum voltage. A capital letter at the end of the 3- / 4-digit code represents capacitor tolerance.
