Intertechnik LUT32/012/10 | 0,12 mH | 0,19 Ω | 3% | 18 AWG

The Intertechnik LUT32/012/10 air core inductor is a precision component designed for high-fidelity loudspeaker crossover networks. Its 0.12 mH inductance value, combined with a tight ±3% tolerance, ensures accurate frequency filtering, making it an ideal choice for audiophiles and DIY speaker builders who demand consistent, repeatable performance in their designs.

This inductor excels in crossover applications where low distortion and signal purity are paramount. Whether you are constructing a new set of bookshelf speakers, upgrading an existing two-way system, or fine-tuning a multi-driver array, the air core construction eliminates core saturation and hysteresis effects, preserving the integrity of your audio signal. It is particularly well-suited for tweeter and midrange filters where even minor non-linearities can be audible.

Constructed with 18 AWG wire, the coil offers a low DC resistance of just 0.19 Ω, minimising power loss and maintaining amplifier damping factor. The 32 mm outer diameter and 12 mm recessed mounting hole allow for secure, space-efficient installation on your crossover board. With a total height of 26 mm and a winding width of 20 mm, this inductor provides a robust, stable form factor. The 5.3 mm centre hole and 15 mm core diameter facilitate straightforward mounting.

Finished to Intertechnik’s exacting standards, this air core roll delivers reliable, long-term performance. Its non-saturating design ensures that your crossover remains linear at all listening levels, making it a trustworthy building block for any serious loudspeaker project.
