VHRF1-28 EMI Filter

Bookmark and Share

The VHRF1 EMI filter is designed to filter the conducted emissions of multiple VHR series DC-DC converters up to its current rating, providing compliance to MIL-STD-461D-F for conducted emissions.

Features:

  • High reliability at low cost
  • Wide input voltage range: 0 to 50V
  • Up to 1.0 Amp maximum current
  • Operation over a -40 °C to +100 °C temperature range
  • 55 dB minimum attenuation at 500 kHz

Compliances and Certifications

  • MIL-STD-1275
  • MIL-STD-704
  • MIL-STD-461 C-F and EN55022 when used with an appropriate VHR DC-DC converter
  • MIL-STD-461C, CS01 and CS02, and MILSTD-461D/E conducted susceptibility requirements when used with a VPT Series DC-DC Converter
