Can I use These ?
I got some huge capacitors, can I use them to filter my PS or something

Re: Can I use These ?
In a computer power supply, you would need to use low-ESR units. Also, these probably won't fit in your power supply.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics. -

Those look like motor kick-start caps... certainly not suitable for computer use.Ludicrous gibs!

IIRC, Mepco Electra's 3186 series was low ESR, by 1980s standards, and 18,000uF is a rather large capacitance.. Unless you work with a mainframe or large serve, these are probably hobby material.PeteS in CA
Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Re: Can I use These ?
Thanks for the kind reply,Pete.
They are actually part of a DIGITAL EQUIPTMENT power supply.
I think it went bellyup.
I was thinking of hanging on to them for a 13.8v dc regulated PS for my CB toys.....which I am using 3-300w computer PS's wired +5+5+5=15v@30A
and the Big caps help the PS's from kicking off when I unkey......so far works really, really good.Comment

PS
If you plan on trying running 2 or more Power Supplies in series snip the ground lugs from the plug and dont let the PowerSupplies touch each other.....Comment

Why not?
Do they die?

Recently acquired one of those silly Logisys acrylic power supplies and lucked into getting one of the "better" ones (most of an input filter, bridge rectifier instead of 4 diode treatment, OK-sized heatsinks, etc.) and wanted to fill out what I can on the board + get some decent caps on there (especially the primary side since I highly doubt the ones in there are actually 1000uf). My questions are:
1. How do I know what components to install re: the input filter? It seem to be missing an X cap, a resistor, and a Y cap.
2. Where can I find a good heatsink for the bridge... -
Hi
I'm trying to locate what i believe to be Radial Electrolytic Capacitors 100v 82uf Non-polar for a Skytec Crossover filter.
Thanks -
I have a question - I have replaced the PSU on my own iMac Pro. However, when removing the motherboard I knocked of a 120 OHM 30% 0.3A small surface mount common mode inductor/filter (~0602 size) in the ethernet circuit near the female RJ45 port.
The closest match I can find on Mouser is 120 OHM common mode inductor at 100MHz - my question is this frequency correct for a motherboard? The schematic for the motherboard only provides '120 OHM 30% 0.3A' and the TDK part number does not return anything in google.
Sorry, I am not experienced hence a basic question.

Disclaimer: This is the first time I step into the realm of analog electronics and my natural language is not English, so please forgive me if I failed to use the correct terms when describing things.
Recently I purchased a Tektronix TDS1012, a 20 years old product for cheap and I thought it could be a nice opportunity for playing (i.e. recapping) and learn something in the process.
The power supply board is exactly the same from this post so I'll just steal it for now.
I'm trying to find replacements for all those Lelon electrolytic caps, but then quickly... -
Hello I have a Marantz sr5012 that I have been repairing. After I have replaced the 2 main filter caps the 2 fuses for the power amplifier blows. The original capacitors are ELNA LAO 10,000uF 71V and the replacements are Nichicon LKS 10,000uF 80V.
I assume a short circuit connection has occurred so I set my multimeter to measure ohms across the 2 fuse connections and both read 55 Kilo-ohms so I assume that is ok.
I am certain that I do not have any bridges on my soldering and after probing around I do find a temporary 0 ohm reading when probing across the positive and negative...
