Due to the steadily growing number of applications that are based on networked communication through data lines, it is becoming increasingly importan to ensure trouble-free operation and protection of electrical systems and devices.
To avoid reduced integrity of the data transfer due to interference and to pass EMC tests, components matched to the data lines are necessary. Implementation is greatly simplified by the filter bags, which contain filter components specially selected for the respective application.

Filter Performance

- Attenuation up to 95 dB due to pi-filter
- Protection of high frequency voltages

High common mode attenuation over wide frequency range due to common mode choke (WE-SL2) and Y-capacitors (WCAP-CSGP)

High differential mode attenuation from 6 MHz due to X-capacitor (WCAP-CSGP)
No influence on the data signal according to RS-485 standard
