I78/680/071 | 6,8 mH | 0,94 Ω | 5% | 21 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, with a precise inductance of 6.80 mH and a DC resistance of just 0.94 Ω, is a high-quality component designed for demanding audio applications. This coil is ideal for use in passive crossover networks within loudspeaker systems, where accurate filtering is essential to ensure clear sound reproduction and proper driver integration. It is particularly well-suited for bass and midrange circuits, where its iron-core construction provides high inductance values in a compact form factor, making it a reliable choice for both DIY enthusiasts and professional audio engineers.

Technically, this coil features a wire diameter of 0.71 mm (Cu), ensuring efficient current handling and low losses. 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 circuit boards or within enclosures. The tolerance of ±5.0% guarantees consistent performance across units, while the robust iron-core design minimises distortion and saturation at typical operating levels. With a DCR of 0.94 Ω, it offers a good balance between low resistance and sufficient inductance for effective crossover design. Whether you are upgrading an existing speaker system or building a new one from scratch, this Intertechnik coil delivers the precision and reliability needed for superior audio performance.
