Intertechnik HQP43/2.2/95 | 2.2 mH | 0.39 Ω | 5% | 19 AWG | Mushroom Core Coil

The Intertechnik Ferrobar mushroom-shaped ferrite core coil delivers exceptional inductance stability for high-fidelity loudspeaker crossover networks. Designed with precision in mind, this 2.20 mH coil ensures consistent audio performance, making it an ideal choice for audiophiles and DIY speaker builders seeking accurate frequency filtering. Its robust construction minimises core saturation and distortion, preserving signal integrity even under demanding conditions.

This coil excels in passive crossover designs, particularly for midrange and bass drivers where reliable inductance is critical. Whether you are upgrading an existing speaker system or building a custom pair from scratch, the Ferrobar coil provides the dependable performance needed to achieve a balanced, natural soundstage. It is also well-suited for use in audio filters and impedance correction circuits.

Technical specifications include a DC resistance of just 0.39 Ω, ensuring minimal power loss, and a generous 0.95 mm copper wire diameter for efficient current handling. The external diameter measures 43 mm with a central hole of 4.8 mm, while the core diameter is 22.5 mm and total height 40.5 mm. The winding width of 30 mm contributes to its compact yet effective form factor. With a tolerance of ±5.0%, this coil guarantees precise inductance values for repeatable results.

Combining meticulous engineering with practical design, the Intertechnik Ferrobar coil is a reliable component for any serious audio project.
