Intertechnik HQP43/1.8/95 | 1.8 mH | 0.34 Ω | 5% | 19 AWG | Mushroom Core Coil

The Intertechnik Ferrobar mushroom-shaped ferrite core coil offers a refined solution for audiophile-grade loudspeaker crossover networks. Engineered with precision, this 1.80 mH inductor ensures accurate frequency filtering, allowing you to tailor the sonic character of your designs with confidence. Its robust construction makes it ideal for both DIY enthusiasts and professional audio engineers seeking reliable performance in passive crossover circuits.

This coil excels in high-fidelity speaker systems where minimal signal degradation is paramount. Whether you are building bookshelf monitors, floor-standing speakers, or custom multi-way arrays, the Ferrobar delivers consistent inductance and stable operation across a wide frequency range. Its low DC resistance of just 0.34 Ω ensures efficient power transfer, reducing energy loss and preserving dynamic range in demanding applications.

Technically, the coil features a 0.95 mm copper wire wound on a ferrite core with a mushroom-shaped profile, optimising magnetic flux and minimising stray fields. The external diameter measures 43 mm, with a central hole of 4.8 mm for secure mounting. The core diameter is 22.5 mm, and the total height reaches 40.5 mm, with a winding width of 30 mm. A tight tolerance of ±5.0% guarantees consistency across units, making it a dependable choice for precise crossover design.

In summary, the Intertechnik Ferrobar coil combines meticulous engineering with practical usability, offering a high-quality component for discerning audio projects.
