I have a linear actuator in which the motor run capacitor has failed.
It's one manufactured by ICAR, marked as follows:-
4 microfarad ECOFILL WB40 400 V B 10.000 h 450 V C 3.000 h Wire connections (though tags would be OK)It's 51mm long and 25mm diameter and can't be any bigger at all because there's a round space that matches its size perfectly in the actuator. Tags instead of wires would be possible but no increase in size is possible. Capacitors with a stud sticking out of the end (which a lot of motor run capacitors have) won't fit.
There's no obvious distributor for ICAR motor start capacitors in the UK, I've tried asking them directly but while they did at least reply they couldn't really help for a one off.
There are *lots* of 4 microfarad 450 volt capacitors to be found but all the ones I can find are fatter and/or longer than I need. Even CPC and Farnell have let me down.
