What voltage is this cap?
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. Thanks, -- John English |

Thanks, That's a damn small capacitance for that size, though I agree with it, so it implies a high voltage to match what you say. I first thought of 123 as meaning 12,000 millivolts, after the convention of 104 for capacitance, but I never heard of anyone actually doing it this way, and it's definitely not 12V. Is the writing clear? Any chance that 123 is actually something else? |

Thanks, -- John English It would have to withstand at least 240*1.41 =340V. I would suggest that it would be a minimum of 400V and possibly 500V. -- Don Kelly remove the X to answer ---------------------------- |

"John E." Axial electrolytic ... ** I bet it is NOT !!! It has no polarity markings - right ? Both ends look the same - right ? Then it is an oil filled paper/film type. " 2J104K " = 0.1uF, 10 % tolerance and probably the 200 volt DC rated. ........ Phil |

In any case, don't these caps have an AC rating rather than a DC rating? - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

Sounds a lot more like a tubular polypropylene/film/wax or similar
capacitor than an electrolytic. Some of the better quality units (safety ratings? Danger, Will Robinson, safety ratings! Especially in a snubber on the AC line!) are in metal cans. Tim. So, how does one decisively determine the type? There are no markings whatsoever other than the ones described. The plastic insulation (shrink) covers all but the inner diameter of the ends. The leads are connected to the (aluminum) end caps which are identical. -- John English |

How about posting a link to a photo of the capacitor?

Given the application, it must be part of some snubber and safety-
rated film caps would certainly be used in such a case. Can you be more specific as to the type? Maybe a reference to a Mouser or Digi-Key item? Thanks, -- John English |

EPCOS B32232 series is an example of a film cap in a metal axial can:
http://www.epcos.com/inf/20/20/db/fc_05/MKT_B32232.pdf Digikey part number 495-3542-ND seems to match your component superficially at least. You will find a lot of film caps with pulse handling capability specifically called out these days. Especially used in switching power supplies and electronic ballasts at line voltage. Tim. Thanks so much for your assistance. Invaluable to one whose knowledge in this area is so... basic. -- John English |

Not possible to be a non-polar electrolytic because these don't usually go above 50Vdc and they are never marked with a voltage code such as 2J. It is most likely a film type with voltage a bit higher than Phil's guess. My own guess would have been 400V but since then we have more info on voltage codes and 630V looks to be the answer. |
