Intertechnik E170/390/300 | 3.9 mH | 0.23 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core inductor, with a precise inductance of 3.90 mH, represents a premium choice for audiophiles and loudspeaker designers seeking uncompromising signal purity. Crafted with meticulous attention to detail, this component ensures minimal distortion, making it an ideal foundation for high-fidelity crossover networks. Its air-core construction eliminates the core saturation and hysteresis effects found in iron-core alternatives, preserving the integrity of your audio signal across the entire frequency spectrum.

This inductor is perfectly suited for use in passive crossover designs within high-end speaker systems, where accurate frequency division is critical. Whether you are building custom loudspeakers or upgrading existing designs, the low DC resistance of 0.23 Ω ensures efficient power handling and minimal signal loss, contributing to a cleaner, more dynamic soundstage. The robust 3.00 mm copper wire winding further enhances current capacity, making it reliable for demanding applications.

Technically, the inductor features a tolerance of ±3.0%, ensuring consistent performance across production batches. Its physical dimensions of 55 x 46 mm allow for straightforward integration into most crossover boards. The E170 core type, combined with the air-core design, guarantees linear behaviour and low eddy current losses. This component is a testament to Intertechnik’s commitment to quality, offering a durable and precise solution for discerning audio projects. Elevate your speaker designs with this exceptional air-core inductor.
