## Old 3-connector capcitor replacement

 Hi, I need to replace a capacitor from an old sewing machine footpedal. The full writing on it says: EROID 0,05 µF + 2 x 1000pF(b)rot 250 V~ -50° / +100° F 1175 E  2 black leads come out of one end, one red lead out of the other. It's one and a quarter inches long, and just under half in inch diameter. The red lead was connected to ground, the black leads to each of the output pins I think that means that it's 0.05µF between the 2 black leads, and 1000pF between the red lead and each of the black leads. I have 3 questions: 1 - Is my analysis of the relative capacitance between the leads correct? 2- Do equivalents of this exist any more? 3- If I can't find an equivalent, can I just make up a triangle of 2 x 1000pF and one 0.05µF as an equivalent? Thanks a lot, Andy [edited to change question 3, and my suggested solution] by OPBoot July 17, 2021 It can be a special topology to accomodate AC voltage (hint, the tilde for the voltage spec), or it can be a mini filter, such as if you search Internet for "murata 3 terminal capacitor". Could not find any info about a company name EROID, but maybe you could be luckier looking for the sewing machine maker. by vanderghast 6 days, 22 hours ago Thanks for the response! I found a photo of a very similar cap, which acutally had the schematic I described printed on the outside, so it seems that they do (or did) exist. So... given that it seems to be only a power smoothing cap, and I've tested the sewing machine with the cap completely removed and it runs fine, I've ordered some individual caps and will give it a go. Yeah - I did ask a forum specifically for this machine, but they're sewing people rather than electronics people, it seems :-) by OPBoot 6 days, 19 hours ago Add comment...
