    Polyester Capacitor ESR

    What should a polyester capacitor 22nf 1000vh ESR should be ? I´m getting ~77 Ohms.

      ESR measurement is irrelevant for caps under 1uF as capacitive reactance at the measurement frequency comes into play too as the capacitance goes lower. Use a regular capacitance meter to measure those.

      A working TV? How boring!

              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...

              Hi
              Measuring a 400v 330uf capacitor across the bridge rectifier and in circuit with a multimeter on ohms. Measures 360 ohms both ways when polarity on the meter is changed. If this is normal, I'd like a brief lesson

              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,...

              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...
