Intertechnik LU25/012/060 | 0,12 mH | 0,32 Ω | 3% | 23 AWG

The LU25/012/060 air core choke coil from Intertechnik is a precision component engineered to elevate the performance of your loudspeaker crossover networks. By utilising an air core design, this coil eliminates core saturation and hysteresis distortion, ensuring a pure, uncoloured signal path that faithfully preserves the integrity of your audio. Its compact construction makes it an ideal choice for audiophiles and DIY enthusiasts seeking to refine the frequency response of multi-driver speaker systems.

This choke coil is perfectly suited for use in high-fidelity crossover filters, where accurate inductance values are critical for achieving seamless driver integration. Whether you are building a new set of bookshelf speakers or upgrading an existing pair, the 0.12 mH inductance and low 0.32 Ω DC resistance work together to deliver precise filtering with minimal signal loss. The ±3% tolerance guarantees consistent performance across production batches, making it reliable for both prototyping and final builds.

Technical features include a 23 AWG wire diameter of 0.6 mm, wound on a 12 mm core with an outer diameter of 25 mm and a total height of 14 mm. The winding width of 8 mm and a central bore of 5.5 mm facilitate straightforward mounting, while the 10 mm recess diameter ensures compatibility with standard crossover boards. This air core roll is a robust solution for demanding audio applications.

With its meticulous construction and transparent sonic character, this Intertechnik choke coil is an excellent investment for anyone serious about loudspeaker design. It delivers the precision and reliability needed to bring your audio projects to life.
