Alpha Core Goertz 0.75mH 14 AWG Copper Foil Inductor

  • DCR: .162
  • Diameter: 2.5”
  • Height: 1.42”


  • Conductor material: 99.9% pure copper foil
  • Conductor dimensions: .003" x 1.00"
  • Coating: .002" thick polypropylene film
  • Leads: No joint, integral design
  • Tolerance: +/- 2.5%


  • Negligible skin effect below 100 kHz; many orders of magnitude below conventional wire-wound types.
  • High winding tension and vacuum fusing of faces provide high dimensional stability, effectively locking the conductors in place. Wire-wound inductors, which allow relative motion of conductors due to electromagnetic forces, will exhibit FM distortion by the process of reactance modulation.
  • Flat inductive reactance from 5 Hz to 50 kHz.
  • No saturation distortion due to air-core design. Inductors contain no magnetic materials.
  • Reduced power loss. Highest space factor (ratio of conductor cross area to total cross-section) means lower DC resistance within comparable dimensions. Negligible power loss due to skin-effect.
  • Extremely low stored charge.
  • Cool operation even during prolonged high output power operation. The high space factor and winding density results in improved heat dissipation.

Foil inductors have obvious advantages over wire-wound inductors in terms of improved electrical and sonic characteristics. This important new development has much to contribute to the design of state-of-the art loudspeaker crossover networks.
