MPE

HEMP Standard Performance Range Up to 3600A

All lines are individually filtered, featuring inductive input to provide both the required transient handling performance and good continuous wave EMC performance even on supplies with low source impedance. The filters are fitted with high-energy transient suppressors and are housed in a compact, RF sealed enclosure in compliance with MIL-STD-188-125-1&-2 and DEF STAN 59-188-1&-2.

Insertion Loss Performance

Asymmetric attenuation shown as measured in 50Ω system, at all loading conditions, in accordance with CISPR-17.
Standard Performance filters meet 100dB attenuation from 30MHz to 18GHz then 90dB attenuation up to 40GHz.

Typical Applications

  • Fixed ground-based C4I military facilities
  • Transportable ground-based C4I military systems
  • MIL-STD-188-125-1&-2
  • DEF STAN 59-188-1&-2 applications
