Intertechnik HQP43/1.0/95 | 1.0 mH | 0.25 Ω | 5% | 19 AWG | Mushroom Core Coil

The Intertechnik Ferrobar mushroom-shaped ferrite core coil delivers exceptional performance for demanding loudspeaker crossover networks. With a precise inductance of 1.00 mH and a tight tolerance of ±5.0%, this component ensures accurate frequency filtering, allowing you to achieve clean, well-defined audio reproduction in your custom speaker builds. Its low DC resistance of just 0.25 Ω minimises signal loss and power dissipation, making it ideal for high-quality audio applications where efficiency and clarity are paramount.

This coil is particularly well-suited for use in passive crossover designs, whether for two-way or multi-way speaker systems, where reliable inductance values are critical for proper driver integration. The mushroom-shaped ferrite core construction reduces external magnetic interference and provides stable performance over a wide frequency range. The 0.95 mm copper wire diameter ensures robust current handling, while the generous 43 mm outer diameter and 40.5 mm total height allow for effective heat dissipation during prolonged use. The 4.8 mm central hole and 22.5 mm core diameter facilitate straightforward mounting onto your crossover board.

Engineered by Intertechnik, a trusted name in audio components, this coil combines precision winding with high-quality materials to deliver consistent, long-lasting performance. Whether you are upgrading an existing speaker system or building a new design from scratch, this ferrite core coil offers the reliability and accuracy required for professional-grade results.
