Intertechnik TRI/HQ40/0.12 | 0.12 mH | 0.033 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 performance from their crossover networks. This 0.12 mH inductor ensures exceptionally clean signal handling, making it ideal for high-fidelity loudspeaker designs where preserving the integrity of the audio signal is paramount.

This inductor is perfectly suited for use in passive crossover circuits, particularly in tweeter and midrange applications where low distortion and precise frequency separation are critical. Its air-core construction eliminates the core saturation and hysteresis effects found in ferrite-core alternatives, resulting in a more transparent and detailed soundstage. Whether you are upgrading an existing speaker system or building a custom design from scratch, this component delivers reliable, audiophile-grade performance.

Technically, the Tritec HQ 40 features a DC resistance of just 0.03 Ω, minimising power loss and ensuring efficient energy transfer. The coil is wound with high-purity Tritec copper wire (7×0.50 mm) for excellent conductivity and low signal degradation. With an outer diameter of 40 mm, a central hole of 5.5 mm, and a total height of 26 mm, it offers a compact yet robust form factor. The inductance tolerance of ±3.0% guarantees consistent and accurate crossover behaviour, making this coil a trustworthy choice for precision audio engineering.

In summary, the Intertechnik Tritec HQ 40 air-core inductor combines meticulous construction with outstanding electrical specifications, providing a reliable foundation for achieving clear, natural sound reproduction in any high-quality speaker project.
