Intertechnik HQP56/8.2/95 | 8,2 mH | 0,85 Ω | 5% | 19 AWG

The Intertechnik Ferrobar mushroom-shaped ferrite core coil delivers reliable, high-quality inductance for demanding loudspeaker crossover networks. With a precise inductance of 8.20 mH and a tight ±5.0% tolerance, this component ensures consistent and accurate filtering, helping you achieve the desired acoustic performance in your designs.

This coil is ideally suited for use in passive crossover circuits, particularly for low-pass and band-pass filters where stable inductance and low losses are critical. Its robust ferrite core construction makes it an excellent choice for both DIY speaker builders and professional audio engineers seeking dependable performance in high-fidelity systems.

Technically, the coil features a DC resistance of just 0.85 Ω, minimising power loss and heat generation. It is wound with 0.95 mm diameter copper wire, offering a good balance between current handling and compact size. The mushroom-shaped ferrite core has an outer diameter of 56 mm, a recess diameter of 25.5 mm, a central hole of 5 mm, and a core diameter of 28 mm. The total height is 35 mm, with a winding width of 23 mm, ensuring a neat and space-efficient fit within your enclosure.

In summary, the Intertechnik Ferrobar HQP56 coil provides the precision and reliability required for high-quality crossover design, making it a valuable component for any serious audio project.
