  • Sturdy structure
  • High inductance, high current, low magnetic loss, low ESR, small parasitic capacitance
  • Flat wire winding, achieve a low D.C. Resistance
  • Temperature rise current and saturation current is less influenced by environment
  • Shield has solderable tabs for additional mounting stability Applications: Designed for high current power supply
