  1. Metal magnetic material (Metal composite)
    Developed magnetic material which has High saturation magnetic flux density and low loss characteristic at high frequency.
  2. Wire wound molding coil
    Wire wound molding coil realizes smaller case size with high inductance value.
  3. Monolithic structure
    Monolithic structure of metal magnetic material and winding wire realizes vibration resistance.
  4. Terminal structure
    1. Gap structure between backside of terminal and core can reduce solder joint crack issue due to thermal stress
    2. Unique terminal structure which has no internal joint can realizes superior vibration resistance.
