Toroidal Common Mode (Three-phase) Choke Coil FW Series LDFW030132YJQH0E

  • AEC-Q200
  • RoHS
  • High Permeability


Compared to the conventional "FL-V series", noise removal has improved in the low frequency range as a result of higher impedance characteristics between 150kHz to 1MHz. The FW maintains high performance in the high frequency range, while additionally supporting a wider range of noise frequency.
