Characteristics

  • Modified internal layout increases the effective suppression range
  • The impedance at 1 GHz are at least 3 times higher compared to the WE-CBF product family
  • Operating temperature: –55 °C to +125 °C

Reference Designs

  • RD016 Reference Design Gigabit Ethernet Front End
  • RD022 GB PoE+-Ethernet-USB“ adapter for industrial use with an EMC perspective

Applications

  • Especially for the suppression of signal lines in the high frequency range
  • For fast data lines: CPU, High Speed bus systems, HDD
