Frequently Asked Questions

Q: How is a C Filter Built?

It is built as a single element: a capacitor from line to ground, with a through wire connecting the input to output. It has attenuation characteristics that increase at 20 dB per decade from its cutoff frequency to at least that frequency where it exhibits a minimum attenuation of 60 dB. It maintains this attenuation at higher frequencies. A feedthrough capacitor filter is usually the best choice for filtering lines that exhibit very high impedance. A feedthrough capacitor, in this website, will be referred to as a C filter.

C-Only Filters are the choice for very high impedance lines.
