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?

Hi everyone.
Recently scored a dead amp from a mackie srm1801 subwoofer and after fixing it, now I'm thinking about a home cinema/party subwoofer project.
Most likely I will use a 15" JBL woofer, which I already have and a diy box.
After reading the mackie user manual, I noticed that it has a 40hz HPF (labeled as "36Hz BUTTERWORTH HPF" in the SM) to protect the speaker from low frequencies. Indeed this seems to be good idea for the intended usage - professional music subwoofer, but bad for movies, where one would expect to "feel" the SUBwoofer.... -
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...
