Products LineupInductors (Coils/Cores)

1 Turn Structure Differential Mode a.k.a. Normal Mode Choke Coil SM Series LESM0301R5P2DV0E

  • AEC-Q200
  • RoHS


Low DC resistance since lead wire only passes through the core. The Iron-based Amorphous Core allows stable operation in high-temperature situations. Compatible with automotive. High safety and reliability standards since there are no layer-short circuits and the magnetic flux leakage is very small.
