Question about capacitor size with same rating
If the capacitor rating is identical but if the replacement capacitor is smaller in size, does it matter?

Re: Question about capacitor size with same rating
If by "rating" you mean capacitance and voltage, it often does matter, because the temperature, impedance, and ripple current rating often matter a lot.
On the other hand, if you are comparing a 30 year old capacitor and a 2021 manufactured capacitor of the same capacitance, voltage, temperature, impedance, and ripple current ratings, the newer part might be smaller, due to technology progress.PeteS in CA

Re: Question about capacitor size with same rating
I'm looking to replace Rubycon 2700uf 6.3v MFZ series and 1500uf 16v MCZ series on an old xbox 360. I couldn't find a datasheet for either rubycon series. Which capacitor brand and series is appropriate for a game console? Would a capacitor labeled for general purpose and with low impendence work?Comment

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.

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... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
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... -
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?
