Intertechnik P62/27.00/095 | 27 mH | 1,76 Ω | 5% | 19 AWG

The Intertechnik Ferrobar mushroom-shaped ferrite core coil offers a robust solution for achieving precise crossover filtering in high-fidelity speaker designs. With an inductance of 27 mH and a DC resistance of just 1.76 Ω, this component is ideally suited for use in passive crossover networks, particularly for low-frequency drivers where accurate signal division is critical. Its ferrite core construction ensures high inductance values in a compact form factor, making it a popular choice among audio enthusiasts and professional loudspeaker builders alike.

This coil is engineered for demanding audio applications, including custom speaker cabinets, studio monitors, and high-end home theatre systems. The mushroom-shaped design, with an outer diameter of 62 mm and a total height of 47 mm, facilitates efficient heat dissipation and stable performance over extended listening sessions. The 0.95 mm copper wire diameter contributes to a low resistance path, minimising signal loss and preserving audio clarity. A central mounting hole of 5 mm diameter simplifies integration into crossover boards, while the recessed diameter of 25.5 mm ensures secure placement.

Technical precision is paramount: the coil features a ±5.0% tolerance, guaranteeing consistent performance across production batches. The winding width of 35 mm and core diameter of 28 mm are optimised for magnetic flux concentration, reducing distortion and improving transient response. Whether you are upgrading an existing design or building from scratch, this Intertechnik Ferrobar coil delivers reliable, high-quality filtering for your audio projects.
