Custom Manufactured HEMP/EMP Filters

Captor Corporation, the expert in electromagnetic interference filters, offers custom HEMP/EMP filters, that target power, signal and tempest interference. We perform the design, engineering, layout, manufacturing and assembly as well as the testing, verification, consulting, prototyping and research and development. We provide assembly of components, connectors, and termination configurations while offering options such as HEMP protection modules, certified PCI data and custom tailoring.

Captor can provide existing designs for power lines, audio-data lines and control-signal lines for AC/DC power, telephone, analog fire alarms, servo motors and synchro transmitters. Ratings are 0 to 480 volts and 0 to 100 amps although higher currents are possible. Utilizing non-nutritive materials, our HEMP/EMP filters can be stored from -55 to +105 °C and are operational from -40 to +71 °C, up to 15,000 feet above sea level and in humidity ranging from 10 to 90%.

Captor can handle quick-turn prototypes up to large-scale production runs with lead times of two to three weeks on stock orders and 10 to 12 weeks for custom orders. For more information on our custom manufactured HEMP/EMP filters please see the chart below or contact us directly.
