The TE (TEMPEST) filter range are designed and tested for shielded room requirements, for attenuation from 14kHz - 18GHz at 100dB. Shielded rooms require high levels of attenuation to ensure no conducted/radiated emissions are either imported or exported from the room. The filters come in 2, 3 or 4 line formats and have current ratings of up to 600 Amps per phase.

Transient suppression can be added as an option to the filters to give protection against induced transients from EMP sources. The filters are housed in stainless steel enclosures that are then plated & painted for protection.
