FS: Small film capacitors (help identify them)

[thomas997]

I have a lot of these small capacitors, and was wondering if anyone would want to buy them or if they are useful at all.

If you just wanted a few I could send them out for free.

Here is a picture:




The box says:
"Philips Components
Made in Belgium
DC Film capacitor
KS axial type
5600pF +/- 2% 63V"

and the capacitors say: "5n6 G63 KSK1"

Too small for bypassing? poly, something else?

Thanks!

Could be useful in active filter circuits. No bypassing or coupling.
Looks like Styroflex. Lead looks more solid than old styroflex units I have seen.
Cheers.

Do you want any?

Hi,

Those caps are indeed polystyrene 2% precision caps as used in frequency correction networks (RIAA, NFB HF correction etc.)
They are still very much sought after as they have a reputation for being (read "sounding") excellent in those types of applications.

Unfortunately, probably for environmental reasons, they have been replaced by much inferior sounding caps in the same range of 63V to 630VDC from a few pF to a couple of nF since 1992 or thereabout.

Lead looks more solid than old styroflex units I have seen.

That's because those are 63VDC ones. The higher voltage values came with thinner leadouts.

As modern electrolytic caps often have much less ESR than their older counterparts you often don't need bypassing in the µF range anymore.
A couple of these polystyrenes will do quite well already....In fact I personally wouldn't waste them in that position anyway but YMMV.

thanks fdegrove.


When I said I had lots, I meant it (hundreds)

Let me know if you want some for free, or to buy some.

Thanks Thomas.
If I were on your continent it would have been nice to get some of those caps.
Mailing to our part of the world is expensive .
Never know what customs will say even though they are far more flexible nowadays.

Hi,

I agree, KS= Polystyrene= Styroflex; there are bad sounding and good soundiog ones out there; the radial types are mostly better and the axial types with excentric leads are better than the ones with centric leads (as yours seem to be) because the internal connection is better in the first cases.

I'd say the only thing to know is to try ...

Cheers

That's always the safest way to be sure but I can ascertain that the ones Thomas997 has on offer here are "the good sounding ones"

Those with a rep for sounding horrible are the shiny, hard plastic ones.
The test is simple enough to do: pull the leadout wires and the entire foil will unroll on the bad ones.

Cheers,
