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.

Captor Corporation manufactures standard, build to print, and custom automated and manual HEMP filters/EMP filters for clients in the military, aerospace, and other critical industries.

HEMP & IEMI Filters

Commercial HEMP Powerline Range

A range of 2 line and 4 line (single & three phase) Power Line HEMP filters meeting the pci requirements of IEC61000-4-24 pulses for severity levels 1 and 2.

Commercial HEMP Equipment Filter

A 10A HEMP equipment filter meeting the pci requirements of IEC61000-4-24 pulses for severity levels 1 and 2. Both lines feature individual inductive input to offer good continuous wave EMC performance and superior transient handling performance even on supplies with low source impedance.

Standard Performance HEMP & IEMI Filter Range

A range of 2 line and 4 line (single & three phase) Power Line HEMP filters independently tested and certified as meeting and exceeding the pci requirements of Mil-Std-188-125-1 and -2 and Def Stan 59-188 parts 1 and 2 for E1 and E2 pulses.

Extended Performance HEMP & IEMI Filter Range

A range of extended performance HEMP filters meeting the pci requirements of Mil-Std-188-125-1 and -2 and Def Stan 59-188 parts 1 and 2 for E1 and E2 pulses but having increased insertion loss performance for applications where additional performance is needed beyond just HEMP requirement.

Standard Performance 1200A Single Line HEMP & IEMI Filter

1200A Power Line HEMP filter independently tested and certified by Jaxon Engineering & Maintenance as meeting the pci requirements of Mil-Std-188-125-1 and -2 and Def Stan 59-188 parts 1 and 2 for E1 and E2 pulses.

Telephone Line HEMP & IEMI Filter Range

A range of HEMP protection filters for telephone lines for use on HEMP protected installations meeting E1 (short pulse) pci requirements of MIL-STD -188-125-1 & -2.

Control Line HEMP & IEMI Filter Range

Ranges of multi-line HEMP protection filters for control lines suitable for use in various HEMP protected installations. All lines are individually filtered and feature inductive input to offer both good continuous wave EMC performance and superior transient handling performance.
