Intertechnik LUT32/015/10 | 0,15 mH | 0,21 Ω | 3% | 18 AWG

Achieve precise crossover filtering with this air core inductor, designed to minimise distortion in high-fidelity speaker systems. The LUT32/015/10 from Intertechnik offers an inductance of 0.15 mH with a DC resistance of 0.21 Ω, ensuring clean signal transmission without the saturation or hysteresis that can plague iron-core alternatives. This makes it an ideal choice for audiophiles and DIY enthusiasts building or upgrading loudspeaker crossovers, where accurate frequency division is critical to sound quality.

Use this inductor in passive crossover networks for two-way or three-way speaker designs, particularly in high-frequency or midrange circuits where low losses and linear performance matter most. Its air-core construction eliminates core-induced distortion, preserving the subtle details in your music. The 18 AWG wire diameter (0.9 mm) strikes a fine balance between current handling and compact form factor, while the ±3% tolerance ensures consistent performance across production batches.

Technical features include a 32 mm outer diameter, 15 mm core diameter, and a total height of 26 mm, with a winding width of 20 mm. The recess diameter measures 12 mm, and the central hole is 5.3 mm, facilitating straightforward mounting on crossover boards. With a resistance of just 0.21 Ω, this inductor minimises power loss, making it a reliable component for high-end audio projects. Whether you are restoring vintage speakers or building bespoke designs, this air core inductor delivers transparent, distortion-free filtering.
