Intertechnik HQP56/3.0/18 | 3.0 mH | 0.33 Ω | 5% | 17 AWG | Mushroom Core Coil

The Intertechnik Ferrobar mushroom-shaped ferrite core coil offers a refined solution for achieving precise crossover filtering in high-fidelity loudspeaker designs. With a nominal inductance of 3.00 mH and a DC resistance of just 0.33 Ω, this component is ideally suited for use in passive crossover networks, where it ensures accurate frequency division and minimal signal loss. Its robust construction makes it particularly effective in bass and midrange driver circuits, delivering clean, controlled performance that enhances overall sound quality.

Technically, the coil is wound with 1.12 mm diameter copper wire, which contributes to its low resistance and excellent current handling capability. The ferrite core, with an outer diameter of 56 mm and a total height of 35 mm, is shaped like a mushroom to optimise magnetic flux and reduce stray fields. The winding width of 23 mm and a centre hole diameter of 5 mm facilitate straightforward mounting and integration into your projects. With a tolerance of ±5.0%, this HQP56 series coil ensures consistent and reliable performance across production batches. Whether you are building custom speakers or upgrading existing systems, this Intertechnik component provides the precision and durability required for professional-grade audio results.
