Intertechnik AT62/082/132 | 0,82 mH | 0,30 Ω | 3% | 16 AWG

The Intertechnik AT62/082/132 air core choke coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its air core construction eliminates core saturation and hysteresis distortion, ensuring pure, uncoloured signal transmission for critical listening environments.

This 0.82 mH choke coil is ideally suited for midrange and tweeter filtering in two-way or three-way speaker systems, where low distortion and linear phase response are paramount. It also excels in high-end subwoofer crossovers requiring tight bass control without magnetic interference. The ±3% tolerance guarantees consistent performance across production batches, making it reliable for both DIY enthusiasts and professional loudspeaker manufacturers.

Technically, the coil features a 16 AWG (1.32 mm) copper wire wound on a 62 mm outer diameter former, with a 28 mm core diameter and 41 mm total height. The 0.30 Ω DC resistance minimises power loss, while the 5.3 mm centre hole and 25.5 mm recessed diameter facilitate secure mounting. The winding width of 35 mm ensures optimal inductance stability.

With its robust build and precise electrical characteristics, this Intertechnik air core coil delivers transparent, dynamic sound reproduction. Whether upgrading existing speakers or building new designs, it provides the accuracy and reliability demanded by serious audio projects.
