Intertechnik LU25/033/050 | 0,33 mH | 0,78 Ω | 3% | 24 AWG

Achieve precise crossover filtering in your speaker builds with this air core choke coil from Intertechnik. Designed for audiophile-grade loudspeaker projects, the LU25/033/050 delivers clean, distortion-free signal handling thanks to its non-saturating air core construction. This 0.33 mH inductor is ideal for use in two-way or three-way crossover networks, where accurate frequency separation is critical to maintaining tonal balance and imaging.

The coil is wound with 24 AWG wire on a 25 mm outer diameter former, offering a compact footprint that fits neatly into tight enclosures. With a DC resistance of just 0.78 Ω, it minimises power loss and ensures efficient energy transfer to your drivers. The ±3% tolerance guarantees consistent performance across multiple units, making it suitable for matched pairs or production runs. A central bore of 5.5 mm and recessed mounting diameter of 10 mm simplify installation, while the total height of 14 mm allows for versatile placement on PCB or terminal boards.

Whether you are designing a new speaker system or upgrading an existing one, this Intertechnik air core choke provides the reliability and sonic transparency required for high-fidelity audio. Its robust construction and precise electrical parameters make it a trusted choice for both DIY enthusiasts and professional loudspeaker manufacturers.
