[sdiy] Sallen Key caps

[Justin Owen]

Hello,

I'm using a Sallen Key LPF as a DAC output reconstruction filter with cutoff set at approx. 500Hz.

I've been using these PET through-hole caps:

Filter works as expected - but I was wondering if these PEN 1210 SMD might be a viable space-saving alternative?

Haven't used a cap like this in surface mount before - so any info would be appreciated.

Thanks,

- J
