Re: Small cap replacements for Sony CRT

50/63/100V film caps with those capacitances should be fine for replacing these (and easy to find too).
The film caps' ESR won't be an issue with any of the CRT circuits - at least I can't think of one.
Most of these small caps are used for signal coupling rather than filtering. And they probably used electrolytics only because they're cheaper.
I'd stay clear of ceramics, though, as some of them have capacitance that is fairly temperature-dependent.

Re: Small cap replacements for Sony CRT
Buy 63v or higher voltage rating capacitors, you don't have to stick to 50v
Just check for 63v rated capacitors on Digikey, and all your values can be found on Digikey.
I would be reluctant to replace them with ceramic or film capacitors, in case the much lower ESR would affect things. Such electrolytic capacitors would normally have something like 1..5 ohm ESR and ceramic and film capacitors have very low esr, under 0.1 ohm typically.Leave a comment:

Re: Small cap replacements for Sony CRT
Ahh. I was probably filtering for Active as opposed to Obsolete but neglected Not for New Designs, and that filter was activated 30 capacitors back. CoolLeave a comment:

Re: Small cap replacements for Sony CRT
What is so special about those caps that you can't use the ones at digikey, I found about 60 of each value at 50volt to choose from

Re: Small cap replacements for Sony CRT
Hmm. Price-wise, perhaps bumping to 100v max would work so long as diameter and lead spacing stays the same? I assume some of the lytics' stats would change a bit, but I don't know off the top of my head how much upping the voltage rating on a low uf electrolytic would affect the applicable circuit.

Small cap replacements for Sony CRT
Hey guys -
I am currently recapping an old Sony Trinitron CRT - some of the caps inside are crusty and have failed while others are just getting a refresh.
I have a list for the primary board, tuner, and neck board, and I need some caps with lower uf values.
50V with 0.1, 0.22, 0.33, and 0.47.
Most of the ones coming up on Digikey are BP caps. There are a few ELNA caps that fit the stats, but - Should I look to jump to something more common like 2.2uf?
I've attached relevant files - a photo of the caps I have left, the XLS spreadsheet with cap data, and schematic of the TV circuit (if interested)Tags: None

by SluggerBI have an old Tivo. The Power Supplies are known to have caps that fail. Here are the caps that come with the original power supply:
I could not find replacement caps with the exact same specs. I followed an online guide and recapped the power supply with caps with these specs
The power supply now works, however the HDMI video is giving me eye strain. I don't know how a capacitor on a Power supply could impact an HDMI video signal, but it does, the Tivo interface has a flicker now and the color/brightness is off. So I want to get some new caps...-
