ST450FRC Series

Common Mode Chokes

ST450FRC Series 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.
  • 50% lower DCR and higher current handling than other CANbus chokes in the market.
  • Filters a broad frequency range of common mode noise.
  • Low profile 1812 footprint: 4.95 × 3.18 × 3.0 mm.
  • Matte tin over nickel over silver-palladium-glass frit terminations.

Notes
  1. When ordering, please specify termination code: e.g. ST450FRC104NRZ.
  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. Current per winding that causes a 25°C rise from +125°C ambient.
  4. DCR is specified per winding, measured at on a Keithley 580 microohmmeter and a Coilcraft CCF 858 fixture.
  5. Winding to winding isolation (hipot) tested for one minute.

Termination:

  • R = Matte tin over nickel over silver-platinum glass frit.
  • P = Tin-lead (63/37) over tin over nickel over silver-platinum-glass frit.
  • Q = Tin-silver-copper (95.5/4/0.5) over tin over nickel over silver-platinum-glass frit.
