Intertechnik LUT32/018/10 | 0,18 mH | 0,23 Ω | 3% | 18 AWG

The Intertechnik LUT32/018/10 air core inductor is a precision component designed for high-fidelity loudspeaker crossover networks. Its air core construction eliminates core saturation and hysteresis distortion, ensuring that your audio signal remains pure and uncoloured. This makes it an ideal choice for audiophiles and DIY speaker builders who demand transparent, accurate sound reproduction from their designs.

This inductor is particularly well-suited for use in passive crossover filters, where it can be employed in low-pass, band-pass, or high-pass sections. Its low DC resistance of just 0.23 Ω minimises power loss and heat buildup, making it suitable for both modest and more demanding speaker systems. Whether you are upgrading an existing pair of speakers or building a new set from scratch, this component will help you achieve a clean, precise frequency response.

Technically, the LUT32/018/10 offers an inductance of 0.18 mH with a tight ±3% tolerance, ensuring consistent performance across multiple units. It is wound with 18 AWG (0.9 mm diameter) wire on a 15 mm diameter former, with an outer diameter of 32 mm and a total height of 26 mm. The central mounting hole of 5.3 mm and a recess diameter of 12 mm simplify secure installation into your crossover board.

In summary, this Intertechnik air core inductor delivers reliable, low-distortion performance for critical audio applications, combining precise electrical specifications with a robust, easy-to-mount design.
