So why use teflon caps in that application?

Hey

Alme look at JCX link nr 3 page 15 -> I could use 10uF for the outputstage and 220nF decoupling with inputstage PSU lines??

Look also at JCX link nr 1 with 10uF and 100nF decoupling

I think it dosnīt matter with 1000uF cap when my shunt reg have 0.01R output impedance down to DC??

What is teflon caps and what can they do that others canīt?

Best regards

Not much. Polypropylene is about the best out there, and cheap to boot.
