Intertechnik TRI62/047/0.50 | 0,47 mH | 0,239 Ω | 1% | 24 AWG

The Intertechnik TRI62/047/0.50 is a precision-engineered air core coil designed for audiophiles and loudspeaker builders who demand uncompromising crossover performance. With an inductance of 0.47 mH and a remarkably low DC resistance of just 0.239 Ω, this coil ensures minimal signal loss and accurate frequency filtering, making it an ideal choice for high-fidelity audio systems. Its ±1% tolerance guarantees consistent, reliable results in critical crossover networks.

This air core coil is particularly well-suited for use in passive crossover designs for bookshelf speakers, floor-standing towers, and studio monitors where clarity and detail are paramount. The low resistance helps preserve the transient response and dynamics of your drivers, while the air core construction eliminates core saturation and distortion, even at higher power levels. Whether you are upgrading an existing design or building a new set of speakers from scratch, this coil delivers the precision needed for a natural, uncoloured sound.

Constructed with 24 AWG wire and a 0.5 mm wire diameter, the coil features an outer diameter of 62 mm, a winding width of 35 mm, and a total height of 41 mm. The central hole measures 5.3 mm, with a recess diameter of 25.5 mm and a core diameter of 28 mm, allowing for straightforward mounting on standard crossover boards. The robust build and tight tolerance ensure long-term stability and repeatable performance, making this coil a reliable component for serious audio projects.

For the discerning listener or builder, the Intertechnik TRI62/047/0.50 offers a perfect balance of low loss, precise inductance, and mechanical integrity, elevating your speaker designs to a higher level of sonic accuracy.
