Intertechnik AT62/120/132 | 1,2 mH | 0,38 Ω | 3% | 16 AWG

The Intertechnik AT62/120/132 air core choke coil is a high-quality component designed for audiophile-grade loudspeaker crossover networks. This 1.2 mH inductor ensures precise filtering, allowing you to achieve clean, accurate sound reproduction in your custom speaker builds or repair projects. Its robust construction and reliable performance make it an ideal choice for both DIY enthusiasts and professional audio engineers seeking consistent results.

This choke coil is perfectly suited for use in passive crossover circuits, where it helps to separate frequency bands and direct them to the appropriate drivers. Whether you are designing a new set of bookshelf speakers, upgrading an existing hi-fi system, or restoring vintage audio equipment, this coil delivers the stability and low-loss performance required for critical audio applications. Its air core design eliminates core saturation, ensuring linear behaviour even at higher power levels.

Technically, the coil features a low DC resistance of just 0.38 Ω, minimising signal loss and heat generation. The inductance value is held to a tight tolerance of ±3%, guaranteeing consistent crossover points. Wound with 16 AWG wire and a wire diameter of 1.32 mm, it offers excellent current handling. The outer diameter measures 62 mm, with a total height of 41 mm and a winding width of 35 mm. The central hole has a diameter of 5.3 mm, and the recess diameter is 25.5 mm, with a core diameter of 28 mm, facilitating easy mounting.

This Intertechnik air core coil combines precision engineering with durable materials, making it a reliable choice for demanding audio projects. Its low resistance and tight tolerance ensure your crossover performs as intended, delivering clear, detailed sound.
