Approvals & Compliances

Feedthrough filters offer a high insertion loss across a broad band of frequencies from a few tens of kHz up to the GHz region. In general feedthrough filters offer a higher level of EMI suppression than feedthrough capacitors of the same current rating. This is particularly relevant to applications where source impedance is smaller than 50 Ω. Different versions are available offering a wide selection on operating currents and performance levels. DC feedthrough filters are designed and approved for 130 VDC/130 VAC 50/60 Hz operation.

Features and Benefits

  • Very low internal series inductance
  • Very high self-resonant frequency
  • Self-healing dielectric
  • High quality and reliability
  • Through-bulkhead mounting
  • Anti-twist protection
  • Custom-specific or dual-versions on request

Typical Applications

  • Power line filter for 48 VDC battery power
  • Increasing system and information security
  • Telecom base stations
  • Switching and cellular equipment
  • Computer servers
  • UPS power supplies
  • Medical equipment
