Product Engineering Drawing

There are several common circuit forms for EMI filters

There are many kinds of internal circuit forms of feedthrough capacitors. The combination of capacitors and ferrite beads according to different circuit structures can form C, LC, Pi, T-type filter circuits. These circuits provide different filtering characteristics. The more components of the filter, the shorter the transition band between passband and stopband, and the greater the insertion loss.

Type C filter, single capacitor structure. It is a low self-induction device that avoids high-frequency noise interference to the ground. It is suitable for signal line filtering and DC power line filtering, and is suitable for applications with high impedance sources and high loads.

LC type filter, this is an EMI filter with inductive and capacitive components. Different installation methods (directions) can be used for occasions with high source impedance and low load impedance, or low source impedance and high load impedance.

The Pi filter is composed of two capacitive elements and an inductive element between the two capacitive elements. Compared with C type, LC type structure provides better high frequency filtering performance. It is suitable for occasions where both the source impedance and load impedance are high and the interference suppression performance is high (insertion loss).

The T-type filter is composed of two inductive elements and one capacitive element. It is similar to the Pi-type filter structure, but it is not as widely used as the Pi-type filter. It is suitable for occasions where the source impedance and load impedance are low, and the interference suppression performance is high (insertion loss).
