Electrolytic Capacitors, Brand: Seatronic

[Clueless but avid]

Hi Folks,



has somene experience with Seatronic Caps? I'm not such a rich man, so I got to look for good offers. Compared to a standard china cap with the same values these are nearly twice as big. I bought 500 for 1€. Hopefully I'm through with buying 2200µ/35V for the next 2 or 3 years.

You can always cut one open and see if there's a smaller cap inside.

You can also measure the capacitance. Even if you don't have a capacitance meter, you should be able to charge the cap with a constant current and measure the time it takes to reach a certain voltage. Or set up an RC filter and measure the cutoff frequency.

At that price, I would assume most are shorted, and most of the non-shorts are open.

Seatronic is a very old name in cheap caps. I find "good deals" on Seatronics in UK hobby magazines from 1977. They do not seem to appear on the Internet (however several non-cap makers use that name, and a PC power supply maker has a similar name).

But hey, take a 24V DC supply and long leads out in your driveway, smoke-test them.

Just out of curiosity,what is the point of ordering a large quantity of an unknown product and THEN asking for opinions? One would think that,as you are not ''such a rich man'',it would be imperative to spend your money wisely in the first place.....

500 for 1€. If I had asked first, they would have been gone.

Sorry,but I think that 500 capacitors (especially 2200µ/35v) for ONE EURO should have raised all kinds of red flags. In any event,good luck.

It was an ebay auction from a private seller. The caps are unused and came in 10 bags with 50 pieces each. I'm gonna look for someone who has a capacitance tester.

when you figure the cost of replacing them when they fail, it's no bargain.
