Intertechnik TRI/HQ40/0.33 | 0.33 mH | 0.055 Ω | 3% | 24 AWG | Tritec Coil

The Intertechnik Tritec HQ 40 air-core inductor is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. With an inductance of 0.33 mH and a low DC resistance of just 0.06 Ω, this inductor ensures minimal signal loss and exceptional transparency in crossover networks. Its air-core construction eliminates core saturation and distortion, making it ideal for high-fidelity audio applications where purity of signal is paramount.

This inductor is particularly well-suited for use in passive crossover designs for bookshelf speakers, floor-standing towers, and studio monitors. It excels in midrange and tweeter circuits, where precise filtering is critical to achieving a seamless driver integration. The ±3% tolerance guarantees consistent performance across production batches, allowing for accurate and repeatable crossover designs.

Technically, the Tritec HQ 40 features a 7×0.50 mm copper winding on a 40 mm outer diameter former with a 5.5 mm centre hole. The core diameter measures 25 mm, with a total height of 26 mm and a winding width of 20 mm. This robust construction ensures 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 Intertechnik Tritec HQ 40 delivers the reliability and performance expected from a leading German manufacturer. Its combination of low resistance, precise inductance, and air-core purity makes it an excellent choice for discerning audio enthusiasts.
