Intertechnik TO10/15 | 15 mH | 0.29 Ω | 5% | 16 AWG | Torobar Toroidal Coil

The Intertechnik Torobar iron-core toroidal coil offers a robust solution for audiophiles and loudspeaker designers seeking precise low-frequency filtering in crossover networks. With an inductance of 15 mH and a generous 1.40 mm copper wire diameter, this coil is engineered to handle substantial current with minimal losses, making it ideal for high-power applications. Its iron-core toroidal design ensures excellent magnetic field containment, reducing interference with nearby components and delivering clean, accurate bass response.

This coil is particularly well-suited for use in passive crossover circuits for woofers and subwoofers, where reliable low-pass filtering is essential. It also excels in custom speaker builds, audio restoration projects, and any application requiring stable inductance with tight tolerance. The ±5.0% tolerance guarantees consistent performance across production batches, ensuring your designs meet exact specifications.

Technical features include a DC resistance of just 0.29 Ω, which minimises power dissipation and maintains signal integrity even at high volumes. The outer diameter measures 93 mm, with a central hole of 5 mm and a total height of 48 mm, allowing straightforward mounting on standard crossover boards. The 1.40 mm copper wire provides excellent current capacity, while the iron core enhances inductance density without excessive bulk. Whether you are upgrading an existing system or building from scratch, this Intertechnik coil delivers reliable, high-fidelity performance.
