Alphacore Inductor 14 awg 3.3mh

Alpha Core Goertz 3.3mH 14 AWG Copper Foil Inductor

• DCR: .421
• Diameter: 3.7"
• Height: 1.42"

Specifications

• 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%

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.
