0.1Uf 700V cap on 1214; can VAC spec be lower?

Postby jeankes » 19 Jun 2018 10:42

Hi guys

restoring a 1214 which is coming together nicely, but still a slight pop on "on / off" so the capacitor across the contacts should be changed.

I looked at the specs and it says 700Vac.... Can someone elaborate on why the voltage rating should be so high?

thanx!

Am not precisely sure why voltage rating should be so high unless it might have something to do with region or extra safety precautions. It would seem that in a 240v region the 275VAC rating would suffice; possible I'm wrong about this. It's important it have a X2 (class 2) safety rating and be in a range of .01uf to .068. Some models have resistors included in the cap; typical example might be Eichoff k005-701/100 (47nf, 100Ω). I read one report which said the 0.68 was more effective than the 0.47.

Possible sources could include Digi-Key.com, Mouser.com, Buerklin GmbH. Might be good to know the best candidates and choices for this application (some precise part numbers), and how important the resistor is to the solution.

I still have some 275vac X2's at hand; hence the question ;)

i'll give it a go, thanks!

>i'll report back if it doesn't work
