680nF Typical value for?

[altec9440]

hello,

I got a surplus stock of 680nF MKP X2.

Evident uses should be capacitive power supply or generic Polypropylene circuits...

Are they typical uses of 680nF caps ?

 

[abraxalito]

Output cap of a classD amp where the partnering inductor is 22uH. This is a typical recommendation for a 4R load, or 8R in BTL.

0.68uFd (680n) was Marshall's choice for a cathode bypass to get a brighter guitar sound than Fender's 22uFd.

I see what abraxalito is saying too.

Otherwise it's kinda an odd or orphan value. 5uFd e-cap is cheaper, "why not use that?"

Arc suppression on mains switch?

Received as gift : so with 100 pieces I need to find uses 😛

with resistor like this :

 

[phase]

A/C line filter, along with a couple of common mode chokes.
