Intertechnik TRI62/039/0.50 | 0,39 mH | 0,209 Ω | 1% | 24 AWG

The Intertechnik TRI62/039/0.50 is a precision-engineered air core coil designed to elevate the performance of high-fidelity loudspeaker crossover networks. As part of the renowned Tritec series, this component ensures minimal signal degradation, making it an ideal choice for audiophiles and professional system builders who demand transparent, uncoloured sound reproduction.

This 0.39 mH inductor is particularly well-suited for use in midrange and tweeter crossover circuits, where accurate frequency division is critical. Its low DC resistance of just 0.209 Ω allows for efficient power handling and reduced energy loss, contributing to a cleaner, more dynamic audio output. Whether you are upgrading an existing design or constructing a bespoke loudspeaker system, this coil delivers consistent, reliable performance.

Technically, the coil is wound with 24 AWG wire to a tolerance of ±1%, ensuring precise inductance values for predictable crossover behaviour. The air core construction eliminates core saturation and hysteresis distortion, preserving signal integrity across the entire frequency range. With an outer diameter of 62 mm, a winding width of 35 mm, and a total height of 41 mm, it offers a robust yet compact footprint suitable for most crossover layouts. The central bore of 5.3 mm and recess diameter of 25.5 mm facilitate straightforward mounting.

Combining meticulous craftsmanship with audiophile-grade materials, this Intertechnik air core coil is a dependable foundation for any serious loudspeaker project.
