Thanks for sharing, George...
I agree 100%... I always replace E-caps with 100 Deg. C caps, with a slightly higher working voltage than the original for a longer life.

Not only do manufacturers try to save money by using parts that are just "good enough". They PLAN for parts to fail a few years after the warranty ends. Its called "Planned Obsoleteness". It keeps their factories producing new replacement products.

I also try to replace with caps rated "Computer Grade", or graded for use in SMPS supplies.

Thanks you Mr. Persico for knowledge and good advise.
How ever, I also would suggest that Capacitors can be replaced with close match but some Area of electronics circuit may be disturbed or not working properly after close match replacement because of micro farads (uf) ratings, like communication areas of circuit in PCB.

thanks you

Agreed...Heat is #1 cause of Electronic component failure in general.

Any electronics exposed to constant environmental heat should be especially suspect (Car Stereo/Audio/CD players/Power amplifiers).
Capacitor failure is often a result of a dried out electrolye in the capacitor causing the plates to short. It isn't uncommon for the interior temperature of most vehicles to exceed 125F (51C) when sitting in direct sunlight for long periods of time.

I did a test on a Whirlpool washing machine. I pulled a 105 cap and substituted it with a 85 degree cap. It worked just fine for a month. The main bearing went out and we got rid of it so I don't know how long it would've lasted. Of course I removed all of the PC boards and kept them for parts and also the pumps.
I agree with you however that the 105's should last longer. All the new caps that I buy will be 105's.
Thanks for the article George.

H Moniem,

It depends on the problem. If the cap always have problem after couple of months you need to replace one that has higher voltage, temperature and also the capacitance (if you wanted to)
