    Need Help with ceramic capacitors

    I have two ceramic capacitors located near the power fet on a psu board that are craced and black looking on the top. The values are as follows:

    47J, 1kv & 12J, 1kv.

    I found one on Mouser but can't find the other. No results on Digi-Key. I
    would like to find them on DK as i am building my order for some fuses, and aluminum caps. Any help would be greatly appreciated.

      A tutorial can be found here'

      For the parts you have, they are respectively 47pF and 12pF, 5%, 1 KV

      Digikey part numbers are 445-2774-ND and 445-2781-ND.

      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.

          Thanks PB. I knew they were PF but i quoted exactly what is on the disc so there would be no mistakes. I like using Digi-Key but was getting no results when i typed in the part #. Not so on Mouser. Brought up the 47pf right off. Figured i would ask the experts hoping you would chime in. Mostly i just read the forums and have no input. I bow to others expertise.
          What ever happened to Dave Max?? Anyway, thanks again.....

              Ceramic capacitors/resistors - do suppliers matter?
              by spleenharvester
              I want to buy one of those SMD component books so I don't have to spend as much time searching my scrap boards for what I need, specifically ceramic caps and resistors as they seem to be what I spend most of my time replacing. But the only ones I can find are no name brands. Does manufacturer matter as much for SMD parts as it does with electrolytics or is the generic stuff likely to be fine?

              Ceramic capacitors half short circuit or full short circuit?
              by samtron786
              Hello
              two small ceramic capacitors with values 040. Can you tell me
              whether they are half short circuit or full short circuit?

              Thank you

              After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
              by dragon3x
              Hi, I have some 32 bits computer motherboards that need repair, as they fail to
              power on.

              Here are some examples :

              (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
              switching supply area).
              (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
              than 6.3 V.)

              1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
              I replaced capacitors with aluminum-polymer.
              3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...

              AA and AAA battery charger capacitors?
              by slybunda
              hey all, iv got my favourite battery charger here which iv had for many years probably 15 years now or maybe even more. it still works good but thought id open it up to clean the dust out of it, lots of dust inside but now its clean and noticed 4 capacitors inside it and wondered if i should replace them.
              it has inside:
              2 x 47uf 16v caps 105c branded as Su'scon (lol sounds sus to me)
              2 x 470uf 16v LZ105c branded as G.Luxon

              not heard of these brands are they any good?

              iv attached photos of the charger and the board inside for an idea on the type of...

              Cyberpower 1500AVR UPS repair
              by quickname
              I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

              Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

              I decided to verify that the batteries were...
