General capacitor question.

[Twisted4465]

Good Morning All,

Kick question I recently received a older plasma tv that no longer works and I opened the back and found a couple capacitors blown/ bulged. I can't find a replacement anywhere online can someone point me in the right direction.

Digi Key or Mouser Electronics.
AND you can also use the wire leaded versions of that radial type of electrolytic capacitor ( s ).

Identical replacements are often an issue.

Provided you obtain a device with a voltage rating of AT LEAST the value being replaced (higher is ok, lower is NOT) you will be good to go.

You can even, in many situations, use alternative values of capacitance as electrolytics often have tolerances ranging from +10 to -50% ..... e.g that 1,000μF could be replaced with a 1,500μF or (less practically, as in PSU's the higher option is preferred) a 680μF or 820μF capacitor.

You can also parallel them for increased capacitance (i.e. 2 x 470μF) and use axial in place of radial and vice versa.

For SMPS applications it is important to have low ESR devices and temperature ranges of 105degC (avoid the 85degC versions).

Radial type doesn't work properly. You can go for Mouser Electronics.

Radial type doesn't work properly.

Why not? The lead spacing is very close. If the ESR isn't exactly the same, it probably is close enough to keep the regulator happy, although the radiated interference might increase a tad.

Looks like Digi-Key part 565-4447-ND might work it is 250V 1000uF and 105°C would just need to verify the 10mm lead spacing is the same.

Here is a link to all the options they have at 250V 1000uF and 105°C one of them should work. Most of the major Distis would have caps at this value. http://www.digikey.com/short/qqd5h3
