I96/3.9/085 | 3,9 mH | 0,52 Ω | 5% | 20 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, with a precise inductance of 3.90 mH and a low DC resistance of 0.52 Ω, is a high-quality component designed for demanding audio applications. This coil is an excellent choice for audiophiles and loudspeaker builders seeking to achieve accurate crossover filtering in their custom speaker designs. Its robust construction ensures reliable performance in both passive crossover networks and other inductive circuits where consistent signal handling is paramount.

This rod coil is particularly well-suited for use in bass and midrange filter sections, where its iron core provides a high inductance value in a compact form factor. The 0.85 mm copper wire diameter ensures efficient current handling, making it ideal for speakers with moderate to high power requirements. Whether you are designing a two-way bookshelf speaker or a more complex multi-way system, this component delivers the precision needed for a clean, natural sound reproduction.

Technical features include a tolerance of ±5.0%, ensuring consistent performance across production batches. The coil measures 36 mm in outer diameter with a 5.7 mm central bore and a total height of 31 mm, allowing for straightforward integration into most crossover boards. The low DC resistance of 0.52 Ω minimises signal loss, preserving the integrity of your audio signal. With its durable iron-core construction and precise winding, this Intertechnik coil offers a reliable solution for achieving accurate crossover slopes and improved speaker performance.
