Capacitor Identification Help

[Joseph Crowe]

I deperately need to identify these two caps so that I can order another pair for the other channel in my system.
I believe the one numbe that is blurred said 186K.

What is this in mfd? is that 1.86mfd?

 

[KatieandDad]

More likely 106K = 10 000 000 pF or 0.01uF
and .........685K = 68 000 00 pF or 0.0068uF

Both look about 250V DC

 

[Frank Berry]

It would be best to measure the value of the caps.

So if both were in parallel then 7.8mfd is the total value? Just making sure!
It makes sense based on what is sounds like in my circuit, giving a 2.7khz crossover point first order butterworth.

 

[Elvee]

Most likely 10µF and 6.8µF/250V, the only unknown is the dielectric.
Probably mylar or polypropylene, but anyway for a Xover it makes very little difference.

0.01uF + 0.0068uF in parallel is 16.8nF.

They look physically too small to be 10uF/250V.

As already mentioned - why not measure them on a DMM with Capacitive scale.

If they are part of a loudspeaker crossover then the 0.01uF and 0.0068uF would be too small.

Although on one of the capacitors the marking is indistinct, let’s assume that they are marked

106K
ME250

and

685K
ME250

This makes the first one 10µF
The K suffix indicates 10% tolerance
And it should be safe to assume 250v DC working.

Likewise the second sample is 6.8µF, 10%, 250v

I think the dimensions look about right for these values.


The dielectric is not known, but my guess would be polypropylene or polyester film.

I do not recognise the manufacturer’s logo to the right of the value code.

ME probably is the series type allocated by this manufacturer.

 

[Joseph Crowe]

ok, well here's a stupid question, if both ends are twisted together, then used in a first order crossover...is that parallel or series?

 

[oiphy]

parallel

 

[Joseph Crowe]

ok, so I'll base it on 16.8uf. I can rig up 16.8uf with some other low quality caps and see if it sounds similar. I don't have a volt meter with a capacitance scale.

 

[Joseph Crowe]

sorry, 16.8 nf.

 

[Joseph Crowe]

or uF?

 

[oiphy]

uf

Need help to indetifiy capacitor

Didn't want to open new thread just to ask if anyone knows what kind (value) of cap is this .15K 400 H20?
I was searching and the closes match i found is this 155MWR400K | MWR Series 400 V 1.5 uF ±10 % Axial Metallized Polyester Film Capacitor | ILLINOIS CAPACITOR - Future Electronics

But not sure if that is right. Thanks for help!

 

[costis_n]

It is 0,15μF. When they say thousands, they mean thousands of picofarads

 

[Jadran]

That was fast, thanks a lot


That's somehow odd to use K instead of pF, or just write 0,15uf
