Axial electrolytic approx 0.5 inch (12 mm) diam, 1.0 inch (25 mm) length
Markings: HGC CP-C 2J104K 123
Google tells me it's a 0.1uF, but I can't find a reference for the "2J" voltage rating. And, any idea what the other markings are?
There are no manufacturer markings (logo, etc.), just plain gray shrink tubing with the above alphanumeric markings.
This is used in a single-phase 240VAC low current box fan speed controller (1 TRIAC is the main current controller).
Any help would be greatly appreciated.
