Signal filters


Forward current: 10 mA ... 0.5 A
Damping adjustment: 50 Ohm ... 600 Ohm
Passband damping: 0.5 dB ... 3 dB
Cut-off frequency: 3.5 kHz ... 1 MHz
Blocking damping: 90 dB ... 130 dB

Especially with signal filters, it is important to tailor the damping curves to the specific application. In the signal range a minimum and smooth passband curve is required, in the cut-off range a high damping is required. For this reason, our signal filters are usually designed as 3-way Pi filters.

For a wide range of applications from control signals in the mains voltage range to digital data transfer via modern bus systems, tesch emc offers customer-specific signal filters.


  • 2-wire analogue signal filter (e.g. control line)
  • 2-wire and 4-wire digital signal filters (e.g. bus systems)
  • Customer-specific housing design, connection technology and performance data


Our signal filters are used in a wide variety of applications. Wherever a standard filter cannot meet your high requirements, we are happy to offer you a tailor-made filter solution.

Ask our engineers and technicians for the customer-specific solution for your task!
