Our filters for TEMPEST and against NEMP (Nuclear Electro Magnetic Pulse) applications are simple to apply. The series, ranging from 6 – 200 [A], provide an attenuation of more than 100 [dB] from 10 [kHz] up to 10 [GHz] as prescribed by the MIL-STD-220A. In normal circumstances these filters cause very little leakage currents. An overload of 1.4 times the nominal maximum current is accepted up to 15 minutes. Due to the rod core inductors an asymmetric load can be applied. Optionally the filter can be supplied as a 400 [Hz] version and/or extra protection against EMP’s.
