Alpha Core Goertz 0.33mH 12 AWG Copper Foil Inductor
- DCR: 0.053
- Diameter: 2.1"
- Height: 2.0"
Specifications
- Conductor material: 99.9% pure copper foil
- Conductor dimensions: 0.003" x 1.00"
- Coating: 0.002" thick polypropylene film
- Leads: No joint, integral design
- Tolerance: +/- 2.5%
Characteristics
- 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.
