Intertechnik I150/18/150 | 18 mH | 0.50 Ω | 5% | 15 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, with an inductance of 18 mH and a DC resistance of just 0.50 Ω, is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker crossover networks. This coil is particularly suited for low-frequency filtering applications, where its iron-core construction ensures efficient energy transfer and precise signal shaping. Whether you are building custom loudspeakers, repairing vintage audio equipment, or upgrading existing crossover designs, this rod coil delivers consistent and reliable results.

Technically, the coil features a copper wire diameter of 1.50 mm, which contributes to its low resistance and excellent current-handling capability. The outer diameter measures 58 mm, with a central hole of 7.9 mm and a total height of 49 mm, making it compact enough for integration into most crossover boards. The ±5% tolerance ensures tight adherence to specified inductance values, critical for maintaining accurate crossover points and phase coherence. With a robust iron core, this coil minimises core losses and distortion, preserving signal integrity across the audio spectrum. Ideal for demanding audio projects, this Intertechnik component combines durability with precision, offering a reliable solution for achieving clean, well-defined bass response in your loudspeaker systems.
