Intertechnik TRI/HQ40/0.56 | 0.56 mH | 0.078 Ω | 3% | 24 AWG | Tritec Coil

The Intertechnik Tritec HQ 40 air-core inductor is a premium component designed for discerning audio enthusiasts and professional speaker builders who demand the highest level of signal purity. With an inductance of 0.56 mH and a remarkably low DC resistance of just 0.08 Ω, this inductor ensures minimal power loss and exceptional transient response in crossover networks. Its air-core construction eliminates the risk of core saturation and hysteresis distortion, making it an ideal choice for high-fidelity loudspeaker designs where clarity and accuracy are paramount.

This inductor excels in a variety of applications, from two-way bookshelf speakers to complex multi-way systems, where precise crossover filtering is essential for seamless driver integration. The 0.5 mm diameter Tritec copper wire, wound in a 7×0.50 mm configuration, provides excellent current handling while maintaining a compact form factor. The external diameter of 40 mm and a central hole of 5.5 mm allow for easy mounting, while the total height of 26 mm and winding width of 20 mm ensure compatibility with most crossover boards. The ±3.0% tolerance guarantees consistent performance across production batches, making it a reliable choice for both prototyping and final builds.

Crafted with Intertechnik’s renowned Tritec technology, this inductor offers superior thermal stability and low eddy current losses, contributing to a clean, uncoloured sound reproduction. Whether you are upgrading an existing design or building a new system from scratch, the Tritec HQ 40 delivers the precision and sonic transparency that serious audio projects demand.
