FreeLists / si-list / [SI-LIST] Re: pcb board capacitors

[Paul Levin <levinpa@xxxxxxxxxxxxx>]

Dear David,

Go to the Johanson Technology website (johansontechnology.com)
and download their free calculator which will show you the
impedance v frequency for their RF capacitors. It will be a
real eye-opener as to how small a capacitor is required to
keep the impedance low out as far as 5 GHz, assuming you need
low impedance from some low frequency to 5 GHz.

Regards,

Paul
