Control Line Hemp/Tempest Filter

Control Line Hemp/Tempest Filter

This MIL-STD-188-125-1 and MIL-STD-188-125-2 compliant Control Line Filter was designed for use on a ground based program for protection of critical systems from HEMP (high-altitude electromagnetic pulse) conditions.

In addition to meeting the MIL-STD-188-125 requirements the filter also has Tempest insertion loss performance. Although originally designed for the ground based program this filter is now used in a number of different installations requiring HEMP protection.
