EDY Posted November 25, 2003 Report Posted November 25, 2003 HiDoes anyone know a good tutorial or something else with explanation of capacitor codes?I have a bunch of them but can figure out their values, like these:F 403ZF 2031042A104K2A472Ketc.It's kinda confuzing Quote
mixos Posted November 25, 2003 Report Posted November 25, 2003 Here is a great article about how to read capacitor codes... http://xtronics.com/kits/ccode.htm Quote
EDY Posted November 26, 2003 Author Report Posted November 26, 2003 Tankx MikeBut help me out just litle more moreAs I figured out the capacitor marked 2A472K should have value +45 deg C +1% and 4,700 pF +-/10%Some may think I'm stupid but I just want to be sure I figured it out just right and what a better way of doing it than consulting someone who knows it better.Cheers ;D Quote
EDY Posted November 26, 2003 Author Report Posted November 26, 2003 :D ;D ;)Mike. Youre the best. Quote
steven Posted January 31, 2004 Report Posted January 31, 2004 :) :) i hope this helps. ceramic capacitor marked 104k, 63, and under it, y5p 104=100,000pf=100nf=0.1uf k= +- 10% tollerance. 63 is for 63 volts. y= - 30 degrees celcious, p= +- 10% stability.ceramic capacitors, with non -linear tempiture coeficients, sometimes use a 3 digit code to indicate there operating tempiture and there stability over that range.the first character like y - 30 degree cellcious. second character 7 thats +125 degree celcious 3rd character p is +/- 10per cent stability. from steven Quote
FireFly Posted February 6, 2004 Report Posted February 6, 2004 Thanks from me also, everyone.Now, if I just had the schematic and PCB layout for the Capacitor Wizard listed at the bottom of the link that mixos gave... ;)http://xtronics.com/capacitor-wizard.htmAnyone have the plans for something similar?

FireFly Posted February 9, 2004 Report Posted February 9, 2004 Not sure if anyone cares about this but I did some digging and found another ESR capacitor meter. It's cheaper than the "Wizard" and has a digital display:http://members.ozemail.com.au/~bobpar/esrmeter.htmIt's available in kit form or preassembled. Testing caps in-circuit sounds like a great idea. Anyone tried this meter? Comments anyone? Quote
Guest Yevgenip Posted March 30, 2004 Report Posted March 30, 2004 usualy, capasitors with a three digit code are most common.the first two digits specify a number and the third is how many zeros you need to add after it. the value is in pF.for example, if you have a capacitor with the code 104, its value is 10 0000 pF.Correct me if I'm wrong.
