Intertechnik LU92/3.3/140 | 3,3 mH | 0,60 Ω | 3% | 15 AWG

The Intertechnik LU92/3.3/140 is a precision-engineered air core coil designed to deliver exceptional audio performance in high-fidelity loudspeaker systems. This 3.3 mH inductor is ideal for use in crossover networks, where accurate filtering is essential to ensure seamless driver integration and natural sound reproduction. Its low DC resistance of just 0.60 Ω minimises signal loss, making it particularly well-suited for demanding applications such as bass and midrange circuits where efficiency and clarity are paramount.

Crafted with a 15 AWG wire diameter of 1.4 mm, this air core coil offers robust current handling while maintaining a stable, non-saturating inductance curve. The outer diameter measures 92 mm, with a recess diameter of 25 mm and a central bore of 5.3 mm, allowing for straightforward mounting in a variety of enclosure designs. The total height of 39 mm and winding width of 33 mm contribute to a compact yet effective form factor. With a tight tolerance of ±3%, each coil ensures consistent performance across production batches, critical for maintaining crossover accuracy. The core diameter of 30 mm further supports reliable operation without the distortion associated with ferromagnetic cores.

This Intertechnik air core coil is the perfect choice for audiophiles and DIY enthusiasts seeking to upgrade or build speaker systems with transparent, detailed sound. Its low-loss design and precise specifications make it a dependable component for achieving refined crossover slopes and superior audio fidelity.
