Replacing a filter capacitor
I have an old bench power supply with a failing filter capacitor. 6800uF 63V radial leads. The closest replacement I've found has "snap-in" terminals, so I'd have to solder some short wire leads to make the connection. Trouble is, while the negative terminal is clearly marked, there are 3 unmarked terminals on the opposite side. Which one(s) do I connect positive to? Looking at the end, with the negative terminal at the 12 o'clock position, the other 3 are at 4:30, 6:00 and 7:30 positions.

A 6800uF 63V radial leaded capacitor is still a popular part. Many places still carry it.
Every capacitor has the connection method printed on it. A snap-in capacitor uses two connections. Usually the extra ones are for extra support. See diagram.

Thanks very much, PJ. I kinda suspicioned 2 pegs might be just for support. The replacement I got is over-spec at 100V and 105C temp, so it's too tall to stand up on the board anyway. Any reason I can't solder some 4" say, 18 guage wires to it and lay it on it's side, with a dab of silicon to keep it from rattling about?
