Intertechnik HQ40/1.8/095 | 1,8 mH | 0,26 Ω | 5% | 19 AWG

The Intertechnik HQ40/1.8/095 Roller Core Coil is a premium iron core inductor designed to deliver precise and reliable crossover filtering in high-fidelity loudspeaker systems. With an inductance of 1.8 mH and a low DC resistance of just 0.26 Ω, this component is ideally suited for use in bass and midrange crossover networks where maintaining signal integrity and minimising power loss are critical. Its robust construction makes it a dependable choice for both DIY audio enthusiasts and professional speaker builders seeking consistent performance.

This coil excels in applications requiring accurate frequency division, particularly in two-way or three-way speaker designs where a clean transition between drivers is essential. The low resistance ensures efficient current handling, reducing heat build-up and preserving the dynamic response of your audio system. Whether you are upgrading an existing crossover or building a new set of speakers from scratch, this component offers the precision needed to achieve a balanced and natural soundstage.

Technically, the HQ40/1.8/095 features a 19 AWG wire diameter of 0.95 mm, wound on a 40 mm outer diameter roller core with a central hole of 5.5 mm and a core diameter of 25 mm. The total height is 30 mm, with a winding width of 20 mm, and the inductance tolerance is ±5%, ensuring consistent performance across production batches. This robust design guarantees long-term stability and minimal magnetic saturation, making it a reliable choice for demanding audio applications.
