Jantzen Audio 000-L-0040 | 0,40 mH | 0,22 Ω | 3% | 15 AWG

The Jantzen Audio 000-L-0040 Litz wire coil is a premium air-core inductor designed for audiophiles and loudspeaker builders who demand uncompromising signal purity. As part of Jantzen’s renowned Litz wax roll series, this component is crafted to elevate the performance of high-fidelity crossover networks, ensuring that every nuance of the audio signal is preserved.

This 0.40 mH inductor is ideally suited for use in passive crossover designs for high-end speakers, where precise frequency filtering is critical. Whether you are upgrading an existing system or building a custom pair of loudspeakers, this coil delivers stable, low-loss performance that minimises distortion and maintains phase coherence across the audio band. Its air-core construction eliminates core saturation and hysteresis, making it a favourite among discerning DIY enthusiasts and professional designers alike.

Technically, the coil features a Litz wire construction with a 15 AWG conductor, which reduces skin effect and eddy current losses at higher frequencies. The DC resistance is a low 0.22 Ω, ensuring minimal power dissipation, while the ±3% tolerance guarantees consistent performance from unit to unit. With dimensions of 48 x 30 mm and a power handling capacity of 4 W RMS, it is compact yet robust enough for demanding applications. The wax-impregnated winding further stabilises the coil and reduces microphonic vibrations.

In summary, the Jantzen Audio 000-L-0040 Litz wire coil offers exceptional build quality and sonic transparency, making it an excellent choice for achieving accurate crossover filtering in high-end audio systems.
