Does anything less than 470uF usually bulge?

    1 So they will fail
    2 because eletrolytics tend to have less resistance across them over ceramics.

    because they are cheaper than polyester or polypropylene more likely.

      Some models.
      Usually called them "Revision Controlled" the last few years.
      I have some Itox Revision Controlled 855GME chipset boards that are really well built.

      Age probably matters too. Itox was slow to adjust for the 'Caps Plague' and I'm pretty sure the company changed hands within the last 2 years.

        On devices such as set-top boxes and DVD players with a separate power supply board, I replace all of the non-quality electrolytics (e.g. unknown brands) on this board.
        For those which has the power supply on the same board, I replace all of the primary side units, along with the units before the output inductor, and those close to the output inductor of each rail, as well as units close to a DC-DC converter.
        My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

          470uf tantalum caps replacement
          by mo000
          hi
          motherboard toshiba C50 PT10F

          i found 2 bad 470uf tantalum in cpu sircuit making short .

          but i only have 380uf tantalum can i replace them with electrolytic caps .

          BenQ GW2450HM - Panel is partially dimmed, works for 2 hours after replacing few caps
          by gumball
          Issue: Panel is partially dark or dimmed, left side is okay (see photos attached).

          Trial: Replaced three visibly bad capacitors on the power supply board (see photos).

          First result: Monitor worked for two hours only. Two capacitors bulged again.

          Diagnosis: After replacing those capacitors the monitor was connected via HDMI cable to a laptop. Laptop was connected to power supply and charging. Power cable was removed from the laptop end and put back. Maybe this was a coincidence but since unplugging the power cable it was noted that the panel had darkened...

          Lowest ESR capacitors, preferably liquid electrolytics but polymer also welcome
          by Perry Babin
          I'm looking for suggestions for electrolytics that are 10mm diameter and up to 25mm tall, through-hole radial capacitors with 5mm lead spacing. The value needs to be in the range of 330uF to 470uF. I typically use 35v caps due to their lower ESR vs 16v caps. Currently, the Panasonic FC is being used but the FM series is under consideration.

          This is for the primary side of a switching power supply in a car audio amplifier.

          Is there a way to calculate power dissipation in a capacitor to predict which will operate at a lower temperature? For example, a 470uF may have a...

          UN55NU7100F failed edge lit LED bar, poor quality replacement LED bar AND bulging cap on PSU
          by howardc64
          Just typical LED bar failure repair but discovered a couple of things worthy of posting



          PSU had a bulging cap (470uF 25V). Likely AC/DC bridge rectifier filter. Have seen a ton of 470uF bridge rectifier filter failures on a bunch of difference devices (not just TVs) Stock up on 470uF 25v 35v



          2nd thing worth of note is after all the work to replace edge lit LEDs. Discovered 2 LEDs with phosphor coating differnce produing slightly differnet color temp. Result on edge lit TV = dark veritical band Can't detect when testing the LED bar along...

          Funai 32FL553P/10 - squealing from PSU, dies after 10 seconds, blank screen after logo, bootloops
          by kotel studios
          Hi,

          Found an Funai 32FL553P/10 TV on sale for cheap listed as broken, so I decided to give a shot at reparing this.

          State I got it in:
          Squealing from the PSU
          After logo I get a blank screen
          After 10 seconds of having a blank display w/ backlight the TV dies
          Give it 7-10ish seconds again and it starts to bootloop.

          What I did so far:
          Replaced all the caps on the PSU (apart from primaries, they were fine and none at hand)
          Checked all voltage rails:
          5VSB - 4.8V
          AMP+13V - 14.4V
          13V - 12.98V (in manual 12V)...
