Foil inductors have obvious advantages over wire-wound inductors in terms of improved electrical and sonic characteristics. 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. 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.
