Intertechnik I78/560/071 | 5,6 mH | 0,85 Ω | 5% | 21 AWG

The Intertechnik Iron-Core Rod Coil, with a precise inductance of 5.60 mH, is a high-quality component designed for demanding audio crossover networks. This coil ensures accurate frequency division, allowing you to achieve clean, natural sound reproduction in your speaker builds. Its robust construction makes it ideal for both DIY enthusiasts and professional loudspeaker designers seeking reliable performance.

This rod coil is particularly well-suited for use in low-pass filter sections of two-way or three-way crossover systems, where it effectively manages bass and midrange drivers. It also excels in series or parallel configurations within complex filter topologies, providing consistent results across a range of speaker projects. Whether you are upgrading an existing design or building from scratch, this component delivers dependable filtering.

Technically, the coil features a 0.71 mm copper wire diameter, which contributes to its low DC resistance of just 0.85 Ω, minimising signal loss and power dissipation. The outer diameter measures 28 mm, with a central hole of 4.5 mm and a total height of 25 mm, allowing for straightforward mounting on your circuit board. A tolerance of ±5.0% ensures that the inductance value remains consistent, critical for maintaining crossover accuracy.

In summary, this Intertechnik iron-core rod coil offers a precise, low-resistance solution for your audio crossover needs, combining technical reliability with ease of integration for superior sound quality.
