Intertechnik I78/150/095 | 1.5 mH | 0.25 Ω | 5% | 19 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, with a precise inductance of 1.50 mH, is a high-quality component designed to elevate your loudspeaker crossover networks. Manufactured by the trusted German brand Intertechnik, this coil ensures accurate frequency filtering, allowing you to achieve a clean and balanced sound reproduction in your DIY audio projects. Its robust construction makes it an ideal choice for both seasoned audio enthusiasts and professional designers seeking reliable performance.

This rod coil is particularly well-suited for use in passive crossover circuits, where it effectively manages the distribution of frequencies to the appropriate drivers—such as woofers and midrange units. Whether you are building a new set of speakers or upgrading an existing design, this component provides the consistency needed for precise audio tuning. Its iron-core construction offers high inductance values in a compact form factor, making it a practical solution for space-conscious enclosures.

Technically, the coil features a DC resistance (DCR) of just 0.25 Ω, minimising signal loss and ensuring efficient power transfer. The winding is made from 0.95 mm diameter copper wire, which contributes to low resistance and excellent current handling. With an outer diameter of 28 mm, a central hole of 4.5 mm, and a total height of 25 mm, it fits neatly onto standard mounting boards. The ±5.0% tolerance guarantees consistent performance across production batches, while the 1.50 mH inductance delivers accurate crossover points for your audio designs.

In summary, this Intertechnik iron-core rod coil combines precision engineering with practical specifications, making it a dependable choice for high-fidelity loudspeaker projects. Its low DCR, compact dimensions, and tight tolerance ensure that your crossover networks perform as intended, delivering clear and detailed sound.
