Intertechnik LU25/005/071 | 0,05 mH | 0,15 Ω | 3% | 21 AWG

The LU25/005/071 air core choke coil from Intertechnik is a precision component engineered for high-fidelity audio applications. This 0.05 mH inductor delivers accurate frequency filtering in speaker crossover networks, ensuring clean signal separation between drivers. Its low 0.15 Ω resistance minimises power loss, preserving the integrity of your audio signal.

Ideal for audiophiles and DIY speaker builders, this coil excels in crossover designs for tweeters and midrange drivers where precise inductance values are critical. It is particularly suited for high-end loudspeaker projects requiring consistent performance and minimal distortion. The air core construction eliminates core saturation, making it perfect for high-power applications where linearity is paramount.

Technically, this choke features a 21 AWG wire diameter of 0.71 mm wound on a 12 mm former, with an outer diameter of 25 mm and a total height of 14 mm. The winding width measures 8 mm, while the central hole diameter is 5.5 mm and the recess diameter is 10 mm. With a tolerance of ±3%, it guarantees reliable inductance stability. The overall dimensions are 61 x 30.2 mm, and the air core design ensures low-loss, non-saturating performance.

This Intertechnik coil is a dependable choice for achieving precise crossover slopes and maintaining audio clarity. Its robust construction and tight tolerances make it a valuable addition to any serious loudspeaker project.
