How to Choose Feedthrough Capacitor When selecting feedthrough capacitors, firstly determine the outline structure diagram and size of the filter according to the size of the space used and the installation method, and select the electrical parameters of the filter according to the voltage level and current level.
Many different types of material can be used to make the feedthrough capacitor, but the most common material today is ceramic. Feedthrough filters are built using a dielectric material that can be shaped into a circular form. This may be in the form of a discoidal (donut shape) or in a tubular form (Fig. 1).
Wiring method: The two feedthrough capacitors are connected in series in the original two lines, the big end pins are respectively connected to the two lead wires on the power board, and the feedthrough capacitors are connected to the corresponding terminals on the other side of the shell. , to supply power to the motherboard.
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.
