Intertechnik HQ43/3.0/095 | 3,0 mH | 0,36 Ω | 5% | 19 AWG

The Intertechnik HQ43/3.0/095 is a premium 3.0 mH iron core coil designed to deliver precise and reliable crossover filtering in high-fidelity loudspeaker systems. As part of Intertechnik’s respected range of roller core coils, this component is engineered to meet the demands of both DIY audio enthusiasts and professional speaker builders who require consistent performance and minimal signal degradation.

This coil is ideally suited for use in passive crossover networks, where accurate inductance values are critical for dividing the audio signal between drivers such as woofers, midranges, and tweeters. Its robust construction makes it a dependable choice for custom speaker designs, repair projects, or upgrading existing systems to achieve cleaner, more defined sound reproduction.

Technical features include a 19 AWG wire winding that provides a low DC resistance of just 0.36 Ω, ensuring efficient power transfer and minimal loss of audio detail. The inductance is rated at 3.0 mH with a tight tolerance of ±5%, guaranteeing consistent performance across production units. The coil has an outer diameter of 43 mm, a core diameter of 22.5 mm, and a total height of 45.5 mm, with a winding width of 30 mm and a central hole of 4.8 mm for secure mounting. The roller core design further enhances magnetic stability and reduces distortion.

With its precise specifications and high build quality, this Intertechnik coil is an excellent choice for achieving accurate crossover points and superior sound quality in any speaker project.
