Intertechnik P62/8.20/132 | 8.2 mH | 0.52 Ω | 5% | 16 AWG | Choke Coil

The Intertechnik Ferrobar mushroom-shaped ferrite core coil offers a refined solution for achieving precise crossover filtering in high-fidelity loudspeaker designs. With its robust 8.20 mH inductance and low 0.52 Ω DC resistance, this component ensures reliable and efficient performance, making it an ideal choice for audiophiles and DIY speaker builders seeking to optimise sound reproduction. Its construction is particularly suited to passive crossover networks where accurate frequency division is critical, as well as in other audio applications demanding stable inductance and minimal signal loss.

Engineered with a 1.32 mm copper winding and a generous P62 ferrite core, the coil delivers consistent electrical characteristics within a tight ±5% tolerance. The mushroom-shaped design, featuring a 62 mm outer diameter, 28 mm core diameter, and 47 mm total height, facilitates efficient heat dissipation and compact integration into speaker cabinets. The 25.5 mm recess diameter and 5 mm central bore allow for straightforward mounting, while the 35 mm winding width ensures optimal magnetic coupling. This combination of technical precision and thoughtful construction makes the Intertechnik Ferrobar coil a dependable component for achieving clear, detailed audio performance in demanding listening environments.
