20 AWG (0.81mm)

ERSE’s ALQ line of air core coils will not saturate or cause any hysteresis distortion. The ALQ line of coils feature our high purity wire to insure maximum signal transfer and fidelity. Each ALQ air core coil is wound with precision layering and electronic tension control, allowing for tightly controlled resistance, self-capacitance and tolerance. The ALQ coils are wound onto custom molded high temperature, rigid polycarbonate bobbins. These bobbins feature a high dielectric strength and are molded with 5mm mounting holes. Finished wrapped with black acetate cloth tape for reduced microphonics and added protection.
