Feedthrough capacitors


Nominal voltage: 24 V ... 6 kV
Nominal current: 50 mA ... 2000 A
Nominal frequency: 50 Hz ... 1 kHz
Test voltage: 100 V ... 12 kV
Cut-off frequency: 10 kHz ... 40 GHz
Damping: up to 130 dB

Feedthrough capacitors in combination with a housing offer protection against common-mode interference, mainly caused by potential differences in the grounding system. The damping is usually not recorded, since the progression is linear. The cut-off frequency must be established in order to determine the beginning of the damping.

Feedthrough capacitors are ideal for shielding applications and are very easy to install. Maximum reliability and a long service life are further quality features.Self-healing film capacitors provide good temperature stability and are very resistant to voltage peaks and failures in critical applications.


  • Connections: Connection wire, plug connection 6.3 mm, soldering tag, connection bolt, copper adapter for busbars
  • Mounting: Contact flange, central screw fixing, D-shape version with anti-twist protection
  • Special solutions in the range of nominal frequencies from 50 Hz up to 20 kHz
