Capacitor question for hardware gurus
« on: October 06, 2007, 02:33:07 AM »
I am finally getting around to repairing my old Televideo computer. I am making a Mouser order and looking at these old capacitor raises a question.

3300uF(M) - What does the M stand for?

Thanks in advance.

Thanks for the responses guys :-) One more question.

I loaded the order with General Purpose Electrolytic Capacitors. One thing I notice is the dimensions available are not exactly the same, all are a bit smaller. That isn't what worries me, I just would like to be sure general purpose is appropriate for the application. I am currently replacing the capacitors on 3 power supplies from this Televideo TS-801H computer.

There is no reason to need anything besides general purpose(20% tolerance) in simple power supplies, right?

Thanks again.

Ok here's a tough one!

Axial capacitor, 25V, 16uF, 85C. It's about 18mm wide, 40mm long. It has "SAMHWA" on it and "(M)8311". Finally the other side says "NPHF"

I cannot find this cap anywhere  :angry: Not Mouser, not Digikey, not ebay. I can't even find anything close. Any ideas?

Ah-ha!!! Is THIS it??


I think so, makes sense as it is on the monitor power supply.

Ordered, hope it is it.

Thank you, but that says 3300uF? This part is 16uF.

Axial are getting harder to get. I am a little worried by the "NPHF" the "NP" series of Samhwa cap is a non-polarised cap.


One small mistake on my part, it is a radial cap, not an axial cap. Brain fart :crazy: I will post a picture later when I get a chance. The cap I ordered is a non-polarised cap. I hope the one I ordered is right, with shipping it cost me almost $12.
