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,

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?

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.

most likely a snubber or bypass cap of some kind.

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.

In the UK where 240V is the norm, 400V would be the normal rating for a
motor start/run cap

0.1uF seems much too small for a motor start/run cap. In any case,
don't these caps have an AC rating rather than a DC rating?

Looking at manufacturer sites, 2J is a common voltage marking for 630V.

1J = 63VDC
2A =100VDC

Poot length? Mine tend to be of the order of 400 milliseconds.

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.

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.

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.
