    Capacitor Temperature Rating

    I've been looking around for an hour or two and there's lots of great information here on capacitors. However, I haven't found much about temperature ratings on caps. I've been mostly looking this up because I found all of the caps on my motherboard that busted are within milimeters from the heat sink and about half a centimeter from my CPU.

    So, is it better to put caps with a higher temperature rating in close proximity to a CPU or is it not really worth the effort?

      Re: Capacitor Temperature Rating

      it's not really worth the effort or extra expense. If the caps around your CPU have failed and you want something a little more robust to heat failures, look into polymer caps. What board are you working with? This can narrow down what mods could be done.

          You won't find much in the way of low ESR caps rated for more than 105C anyway.

              Capacitor detached from PCB – RTX 2070 Super Founders Edition
              by MORETTIGIAN
              Title:
              Capacitor detached from PCB – RTX 2070 Super Founders Edition

              Description:
              During maintenance on an RTX 2070 SUPER Founders Edition, I found a capacitor lying on my desk after reassembly.
              I did not notice it detaching, so I am unsure of its original location on the PCB.

              Procedure performed:
              - Removed backplate
              - Cleaned heatsink and PCB with isopropyl alcohol + soft ESD brush
              - Reapplied thermal compound
              - Reassembled card

              Observed behavior after reassembly:

              Is it no harm to replace with capacitor without ripple current rating?
              by chth96
              When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


              Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
              But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
              Rubycon YK DataSheet (b...

              RTX 3080 FE Identifying capacitor
              by Prolog
              Hi people, I hope this is the correct spot to post this, I'm new to the forum.

              I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.

              I hope these photos make it clear which component I am referring to:
              (yes, the soldering is a bit botched from removing the blown one, I know)

              I have found the board schematic (attached), but there does not seem to be a boardview available. I have never...

              Explanation of capacitor rating
              by Adenitz
              Hello,
              I'm reading an article about the "capacitor plaque" in early 2000s and I have found one sentence I cannot understand.
              The normal lifespan of a non-solid electrolytic capacitor of consumer quality, typically rated at 2000 h/85 °C and operating at 40 °C, is roughly 6 years. It can be more than 10 years for a 1000 h/105 °C capacitor operating at 40 °C.

              What this 2000h or 1000h means? Why 1000h capacitors have longer life span?

              Motor run capacitor physical size vs voltage rating & measurements?
              by Per Hansson
              (TL;DR skip the first paragraph)
              I encountered my first dead motor run capacitor at a customer this week.
              For some fields I guess it is a very common occurrence but the usual way for industrial machines here is to use 3-phase motors.
              (Unless a servo motor makes more sense that is).
              But for some reason this 3-phase machine uses a 1-phase motor for its liquid coolant pump.
              The pump would run but sometimes trip the 10A breaker.
              I monitored it starting and stopping for over an hour until it finally stopped in a specific spot between its windings:
              Then it could...
