Intertechnik LUT44/068/10 | 0,68 mH | 0,50 Ω | 3% | 18 AWG

The Intertechnik LUT44/068/10 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 ideally suited for use in passive crossover designs where precision and low distortion are paramount, such as in high-fidelity home audio systems, studio monitors, and custom speaker builds. It is particularly effective in midrange and tweeter filtering, where maintaining signal integrity is essential for accurate sound reproduction.

Technically, this inductor offers a nominal inductance of 0.68 mH with a tight tolerance of ±3%, ensuring consistent performance across production batches. The DC resistance is a low 0.50 Ω, minimising power loss and heat generation. Wound with 18 AWG (0.9 mm diameter) wire, it handles moderate current levels with ease. The coil measures 44 mm in outer diameter, with a recess diameter of 25.5 mm, a central hole of 5.3 mm, and a core diameter of 28 mm. Its total height is 30 mm, with a winding width of 24 mm, making it compact enough for integration into most crossover boards. This air core inductor delivers stable, low-distortion performance, making it a reliable choice for discerning audio enthusiasts.
