A feedthrough capacitor as a bypass capacitor can make the high-frequency filtering effect very good. This is because the feedthrough capacitor has a very small parasitic inductance and a very low bypass impedance and eliminates high-frequency coupling between the input and output due to the isolation mounting method.
In contrast, a feedthrough capacitor provides superior high-frequency filtering. The feedthrough capacitor has a very small parasitic inductance, a very low bypass impedance, and (because of its isolation mounting) it eliminates coupling between its input and output. For simple, noncritical filtering, discrete filter circuitry can be used.
Tubular feedthrough ceramic capacitors are widely used in high frequency filtering applications. For these capacitors, the inductance is in the series arm of the filter. Due to their cylindrical design, the insertion loss of these capacitors is uniform over a wide range of temperatures.
