SV: 100MFD 55V

Hi, These are oilfilled AC capacitors. Not an electrolytic capacitor. They are usually used together with the motor. Phase-shift capacitor for example to generate a second phase on a single phase system. Do no replace with an electrolytic capacitor. Electrolytic capacitors are DC only. Old DEC equipment contain a lot of them. It is not uncommon to find such capacitors with PCB (Polyclorinathed Bifenyles, if my speeling is correct) in them. Take care if one of these goes into smoke. Burnt PCB produces really lethal dioxines. /Mattis -----Ursprungligt meddelande----- Fr?n: cctalk-bounces(a)classiccmp.org [mailto:cctalk-bounces@classiccmp.org]F?r vrs Skickat: den 4 december 2003 07:49 Till: General Discussion: On-Topic and Off-Topic Posts ?mne: 100MFD 55V Hi, I've got an electrolytic I pulled from my TU56 drive because it had a big crusty electrolyte extrusion through the vent plug in the top. The capacitor is marked "SPRAGUE 100 MFD 55V - 60CY A5030". It is 2" in diameter and just over 4" tall, with two solder lugs on top. I think they are connected to the drive motors. I have looked for replacement electrolytic, but they all have way more capacitance or way more voltage rating, and are nowhere near the right physical dimensions. Is there a source for exact replacements? If not, should I just get one with the right diameter for the mounting clamp and the right capacitance, but some huge voltage rating, or is the voltage rating more important and I should beef up the capacitance instead? Or do I have to get both those right, and substitute a little dinky device? Thanks! Vince
