Intertechnik LUT55/1.2/10 | 1,2 mH | 0,67 Ω | 3% | 18 AWG

The Intertechnik LUT55/1.2/10 air core inductor is a high-quality component designed for audiophile-grade loudspeaker crossover networks. Its air core construction eliminates core saturation and hysteresis distortion, ensuring pure, uncoloured signal transmission for critical listening applications. This inductor is ideal for use in passive crossover designs where precision and low loss are paramount, such as in high-fidelity home audio systems, studio monitors, and custom speaker builds. With a nominal inductance of 1.2 mH and a DC resistance of just 0.67 Ω, it offers excellent efficiency and minimal power loss, making it suitable for both midrange and bass filter sections. The inductor is wound with 18 AWG wire (0.9 mm diameter) on a 28 mm former, with an outer diameter of 55 mm and a total height of 30 mm. Its ±3% tolerance ensures consistent performance across production batches, while the central mounting hole of 5.3 mm and recess diameter of 25.5 mm facilitate secure installation. The winding width of 24 mm contributes to a compact footprint without compromising electrical characteristics. Whether you are upgrading an existing design or building a new crossover from scratch, this air core inductor delivers reliable, low-distortion performance that meets the demands of discerning audio enthusiasts.
