Thermistor Question

What a fine fellow you are. That is exactly the chart I have been looking for.

Such components are, of course, available locally but without this or a manufacturers comparison chart I was struggling.

Thank you

I never thought to try Allproducts, I seem to forget to try outside of the UK

Old chap, you should give the fine fella a GA.

So should you, but I am the only one to do so thus far.

Yeap !

I will now give you the all time best advice for when repairing any SMPS, that you have not had training on, not got the manuals and not got the experience, knowledge and tools:-

Seriously, some can be exceedingly dangerous to long life expectancies.....

GA fixed

Thank you Andy. Good enough advice.

I will go ahead with this as my day job is as an electrician ...so lets just say that although I have little to do with electronics on a daily basis, I have the tools, the test equipment and, as a 50+ year old, I am aware of what electricity can do to the human body (and I have the burn scars to prove it) :)

OC, Andy beat me to it about the "life expectancy" warning...and your response indicates perhaps the nature of the warning; i.e., you know not to work on live equipment (even though you probably do it daily) but have you considered the effect on the life expectancy of the equipment connected to your "repaired" power supply? Andy's advice falls into the same category as advising against repairing a molded case circuit breaker, the Law of Unintended Consequences is most likely to rear its ugly head!

I figure if a 50+ doesn't understand the "ins" and "outs" by now, he will never learn them......let him have a go.

I worked in the computer business years ago and just for fun, tried to repair a few of them, either I did not find the new component for sale, or when I did, it did not fix the problem. Ergo, never managed to fix one.......gave up completely after 5 or 6......%They were just thrown away, not repaired when defective.

In my defense, the chips used were weird, some were unmarked. Several suppliers though I was joking when I found a number as they could not identify the chip or the manufacturer.......how much better the situation today is with the supply of parts I cannot say, my experiences lie at least 10 years ago.

I can say that in my experience, SMPSs are far more reliable than anything I ever used before provided the cooling is good.

You have all the requirements! Have fun!!

I have some of those in my box of parts too but I will happily acknowledge that the complexity of recent computer PSU's is beyond me. Besides I do not know the reason for their demise.

When the switch psu failed I saw what happened and why (a heatsink spring came away from its mount and found its way under the psu during transport) This is the reason I am willing to spend a little time and cash.

What I have just now is almost useless so as far as the equipment is concerned it is already broken....nothing to lose.

As a new member here I find the help and comment wonderful, and open too. I've only found this in a couple of other (computer forum) places.

Bravo all of you.
