Intertechnik LUT55/1.8/10 | 1,8 mH | 0,84 Ω | 3% | 18 AWG

The Intertechnik LUT55/1.8/10 air core inductor is a premium component designed for audiophiles and loudspeaker builders who demand the highest level of signal purity. As an air core roll, it eliminates the core saturation and hysteresis distortion associated with ferrite or iron-core alternatives, ensuring that your crossover networks deliver transparent, uncoloured sound reproduction.

This inductor is ideally suited for use in high-fidelity speaker crossover designs, particularly in midrange and bass filter sections where precise frequency shaping is critical. Its 1.8 mH inductance value makes it a versatile choice for two-way and three-way systems, while the low 0.84 Ω DC resistance minimises power loss and maintains amplifier damping factor integrity. Whether you are building a new set of bookshelf speakers or upgrading an existing design, this component provides the accuracy required for critical listening applications.

Technically, the LUT55/1.8/10 features a 55 mm outer diameter and a 28 mm core diameter, wound with 18 AWG wire (0.9 mm diameter) to a tolerance of ±3%. The total height is 30 mm with a winding width of 24 mm, and the central mounting hole measures 5.3 mm for secure installation. The recessed diameter of 25.5 mm aids in flush mounting. With a robust construction and precise specifications, this air core inductor offers stable performance and low distortion, making it a reliable choice for discerning audio enthusiasts.
