    Help identify SMD capacitor

    Please help identify value of capacitor at C20. On some boards it looks like underlined 1n (1st photo) while on other boards it looks like vu1 without line (2nd photo). Most of the time the color is not tan but lighter grey (better tolerance?). Could it be 1nF or 1000pF perhaps 5% tolerance or better? I'm repairing a board that has it missing and trying to find the value. Next step is perhaps buy a DIY ESR. Thanks in advance.

      Are you by chance blocking photobucket.com? It shows up on my other devices but I went ahead and uploaded directly.

        That looks like 330 stamped right on top of c20. That would be 33pf. the zero is the multiplier

          Black 330 component is a 33 ohm resistor that goes with R17 silk screening. It's the component immediately to the left that I'm after.

            Came across this link that makes a little more sense. Looks like two different marking standards for the same component value. Capacitors usually have a line under and not above so that was part of the confusion whether it was u1 or 1n.

            http://my.execpc.com/~endlr/markings.html

            1st picture
            line above = C0G (NP0) dieletric
            u = 5.6 pF
            1 = 10^1

            2nd picture
            v = 35V
            u = 5.6 pF
            1 = 10^1

            So, it looks like what I need is 56 pF 35V C0G(NP0) dieletric which usually have tight tolerance of 5% or less.

              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...

              Help to identify a laptop mainboard SMD capacitor LA-9982P
              by BlackBurn
              Hello everyone,

              I have an Dell Inspiron 15 3537 laptop mainboard (LA-9982P Rev. 3.0 (A02)) with a blown SMD capacitor as shown in the attached images. However, there is no printed specifications near the capacitor or a codename for the capacitor to identify the specification of the capacitor to replace it. I wonder how to identify the capacitor since the mainboard schematics are also useless as the capacitors are not named on the board. Any help would be highly appreciated.

              Thank You. Stay Safe.

              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,...
