Substitute cap

11-05-2018, 08:50 AM

Hi all,

I have a blown cap from an x-ray power supply. Here is all the writing on it:

1000V-/500v~MP
40/070/56

RIFA T6
PME 261 JA

6800 pF

I can't find the same cap so I was wondering if anyone knew if there was a good substitute for it. How far off 1000v can I go, and how far off 6800 pF? Also, it's a paper film capacitor - if I replaced the same spec with a different type of film capacitor that wasn't paper, would that cause problems?

Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Re: Substitute cap

Thanks Pete. I had seen the Mouser one but there was a minimum order of $1200 for that part!! The Digikey looks promising though so thanks for that.

Sensor on Aurora AS1018CD paper shredder doesn't work

by CapSnap123

I'm getting frustrated troubleshooting a paper shredder. The way the shredder normally works is when you turn the power on, nothing happens until you insert a piece of paper. There is an IR shredder in the shredder and inserting the paper breaks the beam and starts the shredder motor. But now the motor runs constantly, even when no paper is inserted. I've replaced the photodiode and the IR emitter. Also the relay makes a nice clicking sound so I assume it is working too. I don't know what else to check. Here's a photo of the circuit board. The red and black wires marked IR - go to the...

by DexMexDC

Hello, I have one AMD RX 6800 XT and one RX 6700 XT with very similar problem. Both have no GFX and SOC voltage. But lets start with the 6800.

I have experience in electrical engineering and measuring instruments such as multimeters, oscilloscopes, laboratory power supplies, thermal imaging cameras but I just can't get anywhere here.

Let's start with the 6800 XT:
- no visible damage
- No short circuits
- VMEM - 1.35V
- VMEM Controller - 0.89V
- 5V0 - 5.02V
- 0V75 - 0.74V
- 3V3 - 3.27V
- 1V8 - 1.80V
- VDDCR GFX - 0.0V...
