Intertechnik I150/4.7/160 | 4,7 mH | 0,20 Ω | 5% | 14 AWG

The Intertechnik Iron-Core Rod Coil, with a nominal inductance of 4.70 mH, is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. This coil is ideally suited for use in passive crossover networks, where it provides precise low-pass filtering for bass and midrange drivers, ensuring a clean and accurate division of the audio frequency spectrum. Its robust construction makes it a reliable choice for both custom DIY speaker builds and professional audio repair or upgrade projects.

Technically, this coil features a DC resistance of just 0.20 Ω, which minimises signal loss and power dissipation, thereby preserving amplifier efficiency and sonic clarity. The winding is executed with 1.60 mm diameter copper wire, offering excellent current handling and low thermal buildup under demanding conditions. With an outer diameter of 58 mm, a central hole of 7.9 mm, and a total height of 49 mm, it is designed for straightforward mounting on a crossover board. The inductance tolerance of ±5.0% ensures consistent performance across production batches, making this Intertechnik coil a dependable foundation for achieving precise crossover points and superior sound reproduction.
