Ceramic capacitor identification

Post by Lardo Boffin »

I have two ceramic 1uFs in a bag and each has the number 105 on them.

I have a bunch of lose ceramics that fell out of a bag at some point and they also have the number 105 on them.

Lose cap:

Does the number designate its rating? Is it likely to be a 1uF cap? I don’t have anyway of testing it (that I am aware of).

Thanks! And I promise not to let stuff fall out of bags again...

This is a code.
The first two digits are the value. The last digit is the multiplier. The resulting value is in pF

So for “105”...
10 x 100000 = 1000000pF which is 1000nF or 1µF

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb :!:
Looking forward to summer later in the year.
