Hi Red,

Just for general interest, here is a list of capacitor tolerance codes.  Usually, power supply caps have a wide margin for error, unless it's going to be supplying a high frequency device.

Just as a general note, I think the issue that nBit7 is refering to, is that non-polarised caps should not be replaced with polarised caps.  Replacing polarised, with non-polarised would generally be fine.  Non polarised caps are used when the voltage across the cap will have both positive and negative swing.
Good good study, day day up!

If you have a choice, you should go for the 105° types. Electrolytic caps degrade over time and the higher the temperature, the faster they degrade. 105° caps have a slower degradation, i.e. last longer - except where temperature is no issue at all (<40°C).

Axial are getting harder to get. I am a little worried by the "NPHF" the "NP" series of Samhwa cap is a non-polarised cap.


One small mistake on my part, it is a radial cap, not an axial cap. Brain fart :crazy: I will post a picture later when I get a chance. The cap I ordered is a non-polarised cap. I hope the one I ordered is right, with shipping it cost me almost $12.
Someone has to state the obvious and that someone is me!

'M' probably stands for 'Military spec'.
