Caps for CEM & SSM Filters?

Got a quick question: Seems like somewhere I've heard that for CEM based
(and SSM?) filters you're supposed to use polystyrene caps. I can't find
any with values as low as the designs I've been building call for. Here's
what I have found in Mouser's catalog:
"Thomson Ceramic Capacitors
NPO: Class 1
Temperature compensating capacitors, suitable for resonant circuits where
stable capacitance and low D.F. are desired. They are made of non
ferro-electric materials yielding superior stability."
So, can one of you experts tell me if this would be a suitable substitute?
If not, can you tell me what would work?
An unexpected demographic and cognitive constellation co-occurs with
synesthesia: females and non-right-handers predominate, the trait is
familial, and memory is superior while math and spatial navigation suffer.
Synesthesia appears to be a left-hemisphere function that is not cortical
in the conventional sense. The hippocampus is critical for its experience.
Five clinical features
comprise its diagnosis. Synesthesia is "abnormal" only in being
statistically rare. It is, in fact, a normal brain process that is
prematurely displayed to consciousness in a minority of individuals.
