Articles: Capacitor Codes



Most manufacturers stamp codes on the side of their capacitors to help you identify their properties. Listed below are several types of codes, and their meanings.

Tolerance Codes: Temperature Coefficients:
C = +/-.25pf
D = +/-.5pf
F = +/-2%
G = +/-3%
J = +/-5%
K = +/-10%
M = +/-20%
Z = -20% to +80%
NPO: +/-30% from -55c to +125c
X7R: +/-15% from -55c to +125c
Z5U: +22% to -56% from +10c to +85c
Y5V: +/-22% from -30c to +85c
