Intertechnik HQP43/1.5/95 | 1,5 mH | 0,31 Ω | 5% | 19 AWG

The Intertechnik Ferrobar mushroom-shaped ferrite core coil offers a refined solution for audiophiles and loudspeaker designers seeking precise crossover filtering. With an inductance of 1.50 mH and a DC resistance of just 0.31 Ω, this component ensures reliable and efficient performance in a variety of audio applications. Its robust construction makes it ideal for use in high-fidelity speaker systems, where accurate frequency division is critical to achieving clear, balanced sound reproduction.

This coil is particularly well-suited for crossover networks in both passive and active speaker designs, helping to separate audio signals into distinct frequency bands for tweeters, midrange drivers, and woofers. The ferrite core minimises core losses and saturation, while the 0.95 mm copper wire maintains low resistance for optimal signal integrity. The mushroom-shaped geometry, with an outer diameter of 43 mm and a total height of 40.5 mm, allows for efficient heat dissipation and compact integration into enclosures. The central hole of 4.8 mm facilitates secure mounting, and the winding width of 30 mm ensures consistent inductance across the operating range. With a tolerance of ±5.0%, this coil delivers dependable performance for demanding audio projects. Whether upgrading existing speakers or building custom designs, the Intertechnik Ferrobar coil provides the precision and durability required for superior sound quality.
