Electromagnetic interference (EMI) is a disturbance generated by an external source that harms electrical circuits. Conec's filtered connectors mange interference at the signal and power IO. Although they were invented in 1952, the D-SUB is still widely used today. Conec offers both standard filtered D-SUBs, filtered high density D-SUBs, and filtered combination D-SUBs where applications call for power and signal. Conec offers filters in C, LC, and pi filters.

What are filters and what do they do?

C filters are a capacitor-input filter circuit in which the first element is a capacitor connected in parallel with the output of the rectifier in a linear power supply.

LC filters consist of a combination of inductors (L) and capacitors (C) to cut or pass specific frequency bands of an electric signal.

Pi filters will have multiple combinations of component values that all produce the impedance necessary for the given frequency. Pi filters are considered to be more efficient. The Pi filter will also produce a high output voltage with minimal current drain, producing only a very small voltage drop at the output.
