Intertechnik LU25/007/071 | 0,07 mH | 0,18 Ω | 3% | 21 AWG

The Intertechnik LU25/007/071 air core choke coil is a precision component designed for high-fidelity loudspeaker crossover networks. With an inductance of 0.07 mH and a low DC resistance of just 0.18 Ω, this coil ensures minimal signal loss and accurate filtering, making it an ideal choice for audiophiles and DIY speaker builders seeking to optimise sound quality. Its ±3% tolerance guarantees consistent performance across production batches, which is critical for maintaining balanced frequency response in multi-way speaker systems.

This choke coil is particularly well-suited for use in passive crossover designs, where it can be employed for high-pass, low-pass, or band-pass filtering applications. The 21 AWG wire diameter and air core construction eliminate core saturation and distortion, preserving the integrity of audio signals even at higher power levels. The coil's compact dimensions—an outer diameter of 25 mm, a total height of 14 mm, and a winding width of 8 mm—allow for easy integration into tight enclosures. It features a 5.2 mm spade connector for secure and straightforward wiring, while the black finish provides a professional appearance. The central hole diameter of 5.5 mm and recess diameter of 10 mm facilitate mounting on standard crossover boards. Whether you are upgrading existing speakers or building custom designs from scratch, this Intertechnik choke coil delivers reliable, high-performance filtering with exceptional clarity.
