    Recommended Capacitor Tester

    Hello all...

    Was hoping someone could make some suggestions for good, reliable capacitor tester. Is there one out there that can accurately test and provide information about a capacitor such as (capacitance (duh), ESR, Impedance, leakage, etc.) In a different thread, I voiced concern about not being able to accurately identify what specs an old/vintage capacitor had. It occurred to me that if I had a way to comprehensively test an 'original'; identifying the replacement would be cake walk. (I found and bought a few 'general' testers out on eBay and they work OK to provide basic information, but as I mentioned, looking for something that can truly and thoroughly test and measure a capacitor.

      a vintage cap will not be in-spec, so your idea wont work.

              does the peak show leakage?

              nothing that costs 2digit numbers will show ripple btw.

                  I have an old EICO 950B. It works for the stuff I work on, but will only tell capacitance and if it leaks. AND, you can test caps up to 500V for leakage. And it actually supplies 500 volts to the cap.

                      Works well for what I need it for

                          The Peak Atlas ESR 70 is very nice. You can use in circuit, has automatic discharge before it analyzes the capacitor, shows Cap and ESR on a easy to read readout and has a automatic shutoff. Shows In-Circuit/Leaky when it senses a bad cap. I remove and re-test. Nice compact design for the field and gold clips. Different beep tones for each function...love it.

                              Is it possible to test small ceramic disc capacitor with analogue meter?
                              by chth96
                              I read EBOOK of Testing Electronic Component and found that

                              "In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
                              Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
                              It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."

                              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,...

                              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.

                              (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...

                              how can i test individual leds without tester
                              by nubinator
                              Hello I have TCL 65S4 and it has no backlight, seems common problem on this tv to have bad LED's. I have no tester though I thought I could just test each LED with 2xAA batteries for 3v but it doesnt light up at all?
                              I saw a vid with LED tester on this TV and it had 130v for 1 good line which is 24 LEDs does that mean it needs around 5.5v per LED?

                              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...
