How to Read Capacitor Value Codes
This project uses several different kinds of capacitors. Some of these capacitors have their
values and voltage ratings printed on them, others use numerical codes. The diagrams below
will assist you in locating and identifying capacitor values, tolerances, and voltage ratings for
the various circuit requirements for your project.
Sprague “Orange Drop” 715 series – Vintage style film & foil
polypropylene capacitor.
1st line: 715P600V = 715 series; rated at 600V
2nd line: 104J 0821 = value in pfd (104 = 10 and 4 zeros pfd);
tolerance (J = +/- 5%); batch code
104 = .1ufd
103 = .01ufd 223 = .022ufd 473 = .047ufd
102 = .001ufd 222 = .0022ufd 472 = .0047ufd
Cornell-Dubilier Silver Mica – high quality / high accuracy picofarad cap
1st line: 250 +/- %5 = direct value in pfd (250pfd); tolerance 5%
2nd line: 500V SM = voltage rating (500V); batch code
Xicon Metalized Polypropylene – Warm tone, small size
1st line: F104K d = value in pfd (104 = 10 and 4 zeros pfd);
tolerance (K = +/- 10%)
2nd line: 630MPP 1= voltage rating (630V);
construction (MPP = metalized polypropylene)
104 = .1ufd
103 = .01ufd 223 = .022ufd 473 = .047ufd
102 = .001ufd 222 = .0022ufd 472 = .0047ufd
Sozo and Mallory 150 Film and Foil – Vintage style film & foil
polypropylene capacitor, axial leads
1st line: 684K = value in pfd (684 = 68 and 4 zeros pfd);
tolerance (K = +/- 10%)
2nd line: 160V = voltage rating (160V)
3rd line: 0834R = batch / date code
104 = .1ufd 684 = .68ufd
103 = .01ufd 223 = .022ufd 473 = .047ufd
102 = .001ufd 222 = .0022ufd 472 = .0047ufd
