Intertechnik Air Therm heat-resistant coil – 2.70 mH | AT92 | DCR 0.59 Ω | Cu 1.32 mm | ±3.0%

The Intertechnik Air Therm heat-resistant coil offers a premium solution for audiophiles and loudspeaker designers seeking uncompromising crossover performance. Engineered to handle demanding high-power applications, this air core inductor ensures minimal signal degradation and exceptional thermal stability, making it an ideal choice for professional-grade speaker systems and DIY audio projects where reliability is paramount.

This coil excels in passive crossover networks for high-fidelity loudspeakers, particularly in designs requiring precise frequency separation without core saturation. Its robust construction suits both home audio installations and professional sound reinforcement systems, where consistent performance under sustained power is essential. The generous 2.70 mH inductance value allows for effective low-pass filtering in multi-way speaker configurations.

Technically, the coil features a 1.32 mm diameter copper wire wound on a 92 mm outer diameter former, resulting in a low DC resistance of just 0.59 Ω. This ensures excellent signal integrity and minimal power loss. The ±3.0% tolerance guarantees accurate crossover points, while the heat-resistant design maintains stable inductance even under thermal stress. The 30 mm core diameter and 39 mm total height provide a compact yet efficient footprint, with a 5.3 mm centre hole and 25 mm recess diameter for flexible mounting.

Combining robust construction with precise electrical specifications, this Intertechnik Air Therm coil delivers reliable, high-quality performance for discerning audio applications.
