Film Capacitors
Capacitor Question: What is the difference between 2A473J and 2A473K?
I read somewhere that 2A -> voltage = 100volts, 473 = 47000pF or 47nF, K = +/- 10% Tolerance and J = +/- 5% Tolerance. Is this true? I’m not sure about the Voltage 2A if its really 100volts or 50volts and K & J Tolerance? Is there really a big difference with the tolerance K = +/- 10% and J = +/- 5%? especially if I use it in a sound producing device such as tone pots of a guitar? Are these polyester film or mylar? Hoping for your kind replies. Thanks in advance…
To the best of my knowledge, you are right on with all of that. I don’t know what voltage 2A may represent, however. I have not seen this sort of rating on anything other than ceramic capacitors, although it could obviously be used for any. For most applications, the exact dielectric really doesn’t matter.
