    Illinois "PKSM" capacitor

    What is this shit I mean it's some kind of general purpose caps, I know that, but why is there NO datasheet or sometin' when it's manufactured 12. week of 2015? That some daaamn custom part again?

          Too lazy right now, but these're small D5 mm (5 or 7 tall), 22 uF/50 V, all black, PKSM, 105 °C, 1512 manufacturing date, nothing else.

          It's a little update, they used to use some no-name crap in there (Jiang Hai, Jamicon etc.) 22/50 for 85 °C max, but still, replaced them all just to be sure with Chemi-Cons LEs and KMGs (there are two spots where it does not like LEs). One of them already had 3times the ESR of the rest…and I don't particularly trust IC, especially with this they're showing.

          Haven't them been like bought by CDE? It looks to me they changed almost ALL of their series since I've been going through them couple years back.

              One oddity I noticed, looking through IC's products diagram, is that IC's series names are 3-character, not 4-character. So custom? Counterfeit? Quien sabe?

                  Must be custom than. I took another unit as this one likely has bad CPU or something around the way. This time the one in the usual spot was totally done and couple others were bad too so I'll be replacing them as usually with something I trust.

                      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:
                      - GPU powers on and operates normally under...

                      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...

                      Dick Smith Q-1760 linear power supply filter capacitor question
                      by Agent24
                      I have acquired a used Dick Smith Q-1760 power supply - although the OEM is Manson Industrial
                      It has at least one problem.

                      The voltage control potentiometer VR2, 50K is faulty - going high resistance / open circuit in the CCW end and leading to the output voltage jumping around.
                      I have already ordered a replacement potentiometer, so that's not an issue.

                      Now, I want to replace all three electrolytics on the PCB as they are CapXon and I don't trust them so much, I will replace them with something better while I've got the thing apart anyway.
                      All are CapXon...

                      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...

                      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,...
