Hi folks,

Just a quick one. Have a motor start-up capacitor which is dud. See the big bulge at the bottom due to excessive heat. No need to explain why, just curious if this is a polarized or non-polarized variety? I'm thinking it is non-polarized (poly) due to the low capacitance value and AC operating voltage but the red and black wires are the reason for my post.

Any thoughts...

Tnx.

 

With the 500V AC rating that should be a film cap.

Looks like you can get them from many sources including Amazon.

AC capacitors are non polarised. That's why "AC".

With this cap I agree but then why the red and black wires? I think this is more of a curiosity. Is this simply a manfacturing thing...?

 

Yes, Its possible that in manufacturing, the leads may be fabricated for both polarised and non polarised capacitors.
