Anyone tried TDK ceramic disc caps?

I have been shopping for ceramic disc caps and was wondering if these are any good for treble or bright caps, or even snubbers?

They look nice. C0G is a nice rating. Too bad there are no 250pf or 500pf. Especially the 500pf size. Not much available as grid bypass caps in that size. These would look sharp and perform well I think.

Yes as I understand it the temperature coefficient is important particularly in tube amps where there is high heat.
There was a thread that talked about that property and what caps were available.

Here is that thread.

Thanks for the replies.

Structo,
I am very familiar with that thread. I searched Digi Key for a few different possibilities. I ordered some of the TDK's even though the thread seemed to suggest panasonic or CDE. They are very small with fairly short leads.

dogears,
No 250pF or 500pF. I did get some 220pF and 270pF and some 470pF and 560pF, as well as some other values. I was wondering if these values would be close enough to work?

[Structo]

They should be fine.
For me it takes more than a 10% difference (usually 100%) in value to hear, I don't have dogears that's for sure.

I bought some Panasonic Y5U .01uF from Mouser.
These are nice epoxy coated ones I used to bypass my diodes in the power supply.

Part # 667-ECK-A3A103MEH

They don't seem to have the common values of those either.
