Dayton Audio 20 gauge air core inductors are a great choice and the best value for building high quality crossovers. Features fully annealed refined copper wire, perfect layer windings and air core construction to ensure no hysteresis and saturation distortions.

Specifications: • Inductance: 1.0 mH • Wire gauge: 20 AWG • Core type: Air • DC resistance: 0.73 ohms • Tolerance: ±5% • Power handling: 200 watts RMS • Dimensions: 1.6" Ø x 0.66" H (41 x 16.9 mm.)

Copper quality/purity: The copper used in all Dayton Audio inductors, both wire and foil based, is a minimum of 99.9% pure, providing 100% conductivity. The oxygen component of the copper is between 0.02% and 0.04%.

Technical note: To prevent crosstalk and noise position inductors in crossovers at right angles to each other.
