These filters consist of two elements, one inductor and one capacitor. The theoretical insertion loss is 40 dB/decade.
For optimum performance the filter must be place with the inductor situated on the side which has the lower impedance.
These filters are ideal for circuits with different source / load impedances.

FILTERS CONFORMING TO STANDARD AIR 2021 E or EN 2282 and AIR 7305
The aim of standard AIR 2021 E or EN 2282 is to define inflight networks and a certain number of conditions of compatibility applicable to generators, (in flight and ground), to interfaces and functional equipment. It deals with a.c. networks with fixed frequencies (115 Vrms 400 Hz) and d.c. networks (28,5 Vdc) as well as the conditions when these serve in back-up functions. Standard AIR 7305 deals with test procedures of electric generation or equipment performance, however the specifications of electric generation and equipment must be compatible with AIR 2021 E or EN 2282 standard. Filters conforming to these two standards carry the prefix A and are specially manufactured with a view to their use in in-flight networks. They are systematically tested by means of voltage generators designed by our Engineering Department. For the characteristics of transients and subtransients it is necessary to refer to standard AIR 7305.
