Help identifying a capacitor
« on: October 27, 2014, 09:19:51 pm »
Hi there and yes, you guessed it, another stupid question from me. I'm still struggling to identify some components and todays little puzzle is below
I measured the part at 151 nF on two dmm's, this will probably be off spec as the cassette deck is from 1980 and I need to fix it for my ZX Spectrum project.

If anybody could find the time to educate me on component identification I would be extremely grateful



Thanks in advance for any help guys

If you want to take the average of a number of guesses here's mine: .1 uF / 100nF, 25 Volts.
Although the package doesn't look like 100nF at all the .1 seems to suggest it.

Just wait for a few more and take the average, that should be close enough  ;)

Its markings indicate a capacitor of value 0.1uF and a voltage rating of 25V

I would suggest that it is a non-polarised electrolytic type.

Where in the cassette unit does it reside ?

So you are both right, It makes sense.

I don't think the capacitor in the picture is the problem but because two others had leaked I am replacing the whole lot

Thanks again guys for helping with this

Electrolytic's tend to leak over time as the seal fails.

Look to make sure that it does not have a polarity marking against on of the pins. A stripe indicates negative. No markings suggests a non-polarised type.

Old electrolytics are a liability so if some are leaking I would suggest you change out all that are of the same make, even better replace all electrolytic capacitors if you want to be thorough.
