Military Vehicle and
Low Voltage HEMP Filters

Military vehicles operate in extreme environments, but declining performance is not an option. TSS USA Manufacturing LV line of low voltage HEMP filters meet the following standards for unyielding protection:

  • MIL-STD-188-125-1A
  • UL1283 (in process)
  • MIL-STD-188-125-2
  • Low Voltage Directive
  • MIL-STD-220
  • MIL-F-15733

Aside from external dangers and challenging conditions, military vehicles can become victims to a lack of electromagnetic compatibility, or EMC. The variety of equipment in a vehicle—radar, infrared, weapons, targeting systems, telecommunications, and environmental controls—can give rise to electromagnetic interference (EMI) on a continuous, sporadic, or transient basis as signals in different frequently ranges. In other words, the range of equipment can also be seen as sets of both noise generators and victims of noise.

There are different ways that EMI can propagate through a military vehicle. One where filters can help is through controlling signals on cables and wires that can carry the EMI or act as antennas, broadcasting or receiving the interference. However, no matter what the specific mechanism, the EMI still enters another piece of equipment through a cable or wire. That’s why a filter can be useful because it can prevent the passing on of the unwanted frequencies.

Cost-effective military off-the-shelf grade filters can suppress the EMI signals from even commercial off-the-shelf (COTS) equipment by preventing specified frequency ranges that would be harmful from entering another piece of equipment.

Some solutions are intended to manage EMI from such standard vehicle equipment alternators, wiper motors, blower motors, washer motors, oil cooler fans, air conditioning equipment, engine management systems, and censors to comply with FFR (fitted for radio) requirements.

Other types of filters are intended more for specialized items such as beacons, smoke dischargers, door actuators, turret motors, and ancillary devices like shielded containers, communications devices, and medical equipment.

The low-voltage versions of filters, which run at voltages of up to several hundred volts and typically within ambient temperature ranges of -40°C to 50°C.

TSS USA Manufacturing operations are in the U.S.A. and source raw materials and components predominately from the U.S. to serve your critical operations. TSS filters meet the FAR 52.225-1 Made in America.
