SMD ceramic cap. Which one?

[antomas]

Hi everybody!
I'm searching for a good SMD, small-value (10-47pf), 1206-size, bandwidth limiting capacitor (Clim - see picture).

I couldn't find silver-mica or polystyrene SMD caps, so I think the only possible choice is to use a ceramic capacitor
like the Epcos COG B37940 .
Besides impedance linearity up to very high frequencies (100 MHz?), there is more to consider?
Thanks very much to everyone willing to answer. :-)

COG or NP0 material are OK.
Working voltage should be high enough. There is not
much more to choose.

From Farnell catalog,

1206 size 50V dc. NPO

10pF 360-6030 order code

22pF 360-6041

33pF 360-6053

47pF 360-6065 order multiple= 10pcs.

Gerhardt and Singa,
heartfelt thanks for your kind help, I think I'll try and use the COG caps I mentioned above and eventually the Farnell NPO caps.
Cheers,
Massimo
