Intertechnik HQ43/10/085 | 10 mH | 0,93 Ω | 5% | 20 AWG

The Intertechnik HQ43/10/085 is a premium 10 mH iron core coil engineered to deliver precise and reliable performance in high-fidelity loudspeaker crossover networks. As part of Intertechnik’s respected roller core range, this component is designed for audiophiles and DIY speaker builders who demand accurate filtering and minimal signal degradation. Its robust construction ensures consistent inductance over time, making it an ideal choice for both new builds and upgrades to existing speaker systems.

This coil excels in a variety of crossover applications, particularly in low-pass filters for woofers and subwoofers where higher inductance values are required. The 10 mH rating allows for effective frequency separation, while the low DC resistance of just 0.93 Ω minimises power loss and maintains driver damping. Whether you are designing a two-way bookshelf speaker or a complex multi-way floorstanding system, this coil provides the stability and precision needed for a clean, natural soundstage.

Technically, the HQ43/10/085 features a 20 AWG winding with a wire diameter of 0.85 mm, wound on a roller core with an outer diameter of 43 mm and a core diameter of 22.5 mm. The total height is 45.5 mm, with a winding width of 30 mm and a central hole of 4.8 mm for secure mounting. A tight tolerance of ±5% ensures consistent performance across units, making it a reliable choice for critical crossover designs.

In summary, this Intertechnik iron core coil combines high inductance, low resistance, and precise manufacturing to deliver exceptional value for serious loudspeaker projects. Its technical specifications and build quality make it a dependable component for achieving accurate, high-quality audio reproduction.
