Capacitor Testing

08-30-2009, 08:09 AM

A simple question for the more electrically inclined than me...

I had to get a new multi-meter recently and this one has a CAP setting for capacitors which measures uF. It also says that it can be used for diodes and transistors but I'm not sure what it would do. The limit of my repairs so far have been replacing capacitors and CCFLs but would any of these features ease my troubleshooting instead of the replace and see method that I have used?

The capacitance feature won't be much help. A capacitor can gave a high ESR while still showing normal capacitance.

Of course, the ohmmeter function and the diode test will be useful for finding shorted transistors and open fuses.

The Voltage function will qouckly show if the power supply is working.

For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

Microwave Oven Capacitor Testing

by genuineguy

Hello Experts
Need help with my experiment to test a Capacitor from microwave oven

Its a High voltage capacitor. 1mfd, 2100V AC.

A DMM test across its terminals show infinite/open resistance.

The capacitor has a 10Mohms shunt resistor internally.

1. Connected 100w bulb in series to the capacitor. AC supply 230v connected. The bulb did not light up. This proves the capacitor is NOT shorted

2. Connected capacitor in series with a diode and 10ohm, 10W resistor. Connected AC supply 230v. I was hoping DC voltage reading...

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...

If I replace with inferior capacitor, Is it No harm to other IC components at all?

by chth96

I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor...

KDM 480W PSU upgrade succes! (opinions?)

by bauto601

Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps

The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....

How can I test non-polarized capacitor?

by chth96

I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm

And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,...
