I’ve got a couple of these that need replacing on standup targets on a Seawitch. I want to make sure I’m identifying the part correctly and ordering a suitable replacement.

I’m reading this as being a .05uf 100v ceramic disk capacitor. Is that right?

The closest thing I’ve been able to find at Mouser is this:

It’s a higher voltage unit, but that should be okay, right?

Yes, you can go higher voltage

.05Mf not .05uF

.05Mf not .05uF

I thought the M after .05 was the tolerance? (20%)

Either is ok

Huh ... guess I learnt something https://www.westfloridacomponents.com/blog/is-mf-mfd-the-same-as-uf/

thanks .... a higher voltage rating is ok

Can you use a .047 like they use on Bally machines?

I could be wrong (which is why I’m asking for advice), but those are a lower voltage rating. I think you can go higher voltage rating, but not lower?

Yes, but these are for stand up targets.

You are correct here based on the original components but I was wondering if the original component was a higher voltage than it needed to be. Older Ballys and older Sterns share a lot of similarities and you can use the same mpus on each so I assume the voltages may be similar as well. Can someone with more knowledge confirm or deny this?

Found an exact replacement (.05M 100v) on EBay. Thanks for pointing me in that direction. It seems that these capacitors are used in Fender guitars as well.
