Intertechnik E106/039/300 | 0,39 mH | 0,06 Ω | 3% | 9 AWG

The Intertechnik Air-core Coil, with a precise inductance of 0.39 mH, represents a premium choice for audiophiles and loudspeaker designers seeking uncompromising signal purity. This high-quality component is specifically engineered for use in passive crossover networks, where accurate frequency filtering is essential to achieve a balanced and natural soundstage. Its low direct current resistance of just 0.06 Ω ensures minimal power loss, making it ideal for high-fidelity audio systems where every detail matters.

Constructed with a 3.00 mm diameter copper winding, this air-core coil delivers exceptional conductivity and thermal stability, reducing the risk of distortion even under demanding conditions. The generous 80 x 55 mm dimensions and 61 mm total height accommodate the robust winding, while the ±3% tolerance guarantees consistent performance across production batches. Unlike iron-core alternatives, the air-core design eliminates core saturation and hysteresis effects, preserving the integrity of the audio signal from the amplifier to the drivers.

Whether you are building custom loudspeakers or upgrading existing designs, this Intertechnik coil offers reliable, low-loss operation. Its foil-type winding further enhances current handling, ensuring long-term durability. For discerning listeners and engineers alike, this component provides the precision and transparency required to refine any crossover network.
