Hello fellow DigiKeyers!
Background: servicing an AKAI cassette deck manufactured in 1979 or 1980. Pet project and I’m just a hobbyist. Photos below.
I have this capacitor here that has no polarity markings. I have the service manual for the power supply that this capacitor came out of ask well. The service manual schematic also confirms that the capacitor is non-polar.
Markings are clear about the rated capacitance and voltage. No problem there. I’m just a bit stumped on the composition of the capacitor, whether the capacitor should be replaced due to its age, and what to replace it with. It’s a strange form factor, so that has me second guessing myself.
My guesses and tests so far:
- It’s clearly non-polar as confirmed from the component’s markings and the service manual’s schematic
- It could be a film capacitor, leading me to think; I’m not worried about any electrolyte degradation, so there’s no need to replace it
- Component tester does confirm the value for rated capacitance is still measuring to spec.
- The capacitor is not conductive between its terminals
So here’s the question for the group; any idea what this capacitor’s construction is?
If it was your project; would you replace the cap?
Thanks for your input.
