Intertechnik LU25/008/071 | 0,08 mH | 0,19 Ω | 3% | 21 AWG

The Intertechnik LU25/008/071 air core choke coil is a precision component designed to elevate the performance of high-fidelity loudspeaker systems. As an air core inductor, it eliminates core saturation and hysteresis distortion, ensuring pure, uncoloured signal transmission for critical audio applications. This 0.08 mH choke is ideally suited for use in crossover networks, particularly for tweeter circuits or high-pass filter sections where low inductance values are required to achieve accurate frequency division. Its compact construction also makes it an excellent choice for custom DIY speaker projects or upgrading existing designs where space is at a premium.

Technically, this coil features a low DC resistance of just 0.19 Ω, minimising power loss and heat generation, while the ±3% tolerance guarantees consistent performance across production batches. Wound with 21 AWG wire (0.71 mm diameter), the coil has an outer diameter of 25 mm and a total height of 14 mm, with a winding width of 8 mm. It is designed for secure mounting via four 4.2 mm fixing holes on a 37 mm depth footprint, and the central bore of 5.5 mm accommodates standard fixing hardware. With a maximum power handling of 40 W, this air core choke delivers reliable, distortion-free operation, making it a trusted choice for discerning audio enthusiasts and professional designers alike.
