Intertechnik Air-core Coil – 3.00 mH | LU92 | ±5.0%

The Intertechnik Air-core Coil, with a precise 3.00 mH inductance, is an essential component for audiophiles and speaker builders seeking to elevate their audio systems. Designed to deliver accurate crossover filtering, this coil ensures that each driver in your loudspeaker receives only the frequencies it is best suited to handle, resulting in a remarkably clear and balanced soundstage. Its air-core construction eliminates the risk of core saturation, making it ideal for high-fidelity applications where signal purity is paramount.

This coil is perfectly suited for use in passive crossover networks within high-end home speakers, studio monitors, or custom DIY audio projects. Whether you are refining a two-way bookshelf design or constructing a complex multi-way system, the 3.00 mH value allows for precise frequency separation, ensuring smooth transitions between woofers, midranges, and tweeters. The ±3% tolerance guarantees consistent performance across production runs, which is critical for maintaining phase coherence and tonal accuracy in matched pairs.

Technically, the coil features a wire diameter of 0.72 mm, offering an excellent balance between low DC resistance and manageable physical size. With dimensions of 24 x 38 mm, it is compact enough to fit into most crossover boards without crowding. The air-core design, as opposed to iron-core alternatives, provides linear inductance over a wide frequency range, minimising distortion and preserving the natural character of your music. This coil is a reliable choice for discerning listeners who demand transparency and precision from their audio components.
