1812CAN Series

Common Mode Choke

RoHS compliant halogen free AEC-Q flag
Our 1812CAN Series filters a broad frequency range of common mode noise with 50% lower DCR and higher current handling than other CANbus chokes in the market. They are designed for common mode noise suppression on CAN or CAN FD lines in automotive or general industrial automation applications, and can also be used for FlexRay automotive bus systems.
  • Inductance values from 11 µH to 100 µH
  • Filters a broad frequency range of common mode noise
  • 50% lower DCR and higher current handling than other CANbus chokes in the market
  • Designed for common mode noise suppression on CAN or CAN FD 
    in automotive or general industrial automation applications
  • Can be used for FlexRay automotive bus system
  • Low profile 1812 footprint: 4.95 × 3.18 × 3.0 mm
  • AEC-Q200 Grade 1 (−40°C to +125°C)

Notes
  1. When ordering, please specify packaging code: e.g. 1812CAN-104NRC
  2. Inductance is per winding, measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter and a Coilcraft CCF 1113 fixture.
  3. Max current that may be applied at +125°C
  4. DCR is specified per winding, measured 25°C on a Keithley 580 micro-ohmmeter and a Coilcraft CCF888 fixture. For other operating temperatures, use this DCR at Temperature calculator.
  5. Winding to winding isolation (hipot) tested for one minute.
