Jantzen Audio 000-1839 | 0,39 mH | 0,42 Ω | 3% | 20 AWG

The Jantzen Audio 000-1839 air core coil is a high-quality component designed for audiophiles and speaker builders who demand precision in their crossover networks. With an inductance of 0.39 mH and a DC resistance of just 0.42 Ω, this coil ensures minimal signal loss and accurate frequency filtering, making it an excellent choice for both DIY projects and professional loudspeaker designs.

This air core coil is ideally suited for use in two-way or three-way speaker systems where clean, transparent sound reproduction is essential. Its non-magnetic construction eliminates core saturation and hysteresis distortion, preserving the integrity of the audio signal. Whether you are upgrading an existing design or building a custom crossover from scratch, this coil delivers reliable performance across a wide range of applications.

Technically, the coil features a 20 AWG copper wire with a diameter of 0.81 mm, wound to a tolerance of ±3% for consistent electrical characteristics. The compact dimensions of 31 x 15 mm allow for easy integration into tight enclosures. As a true air core design, it avoids the nonlinearities associated with ferrite or iron cores, ensuring low distortion and stable inductance over varying current levels.

In summary, the Jantzen Audio 000-1839 air core coil combines precise specifications with robust build quality, making it a dependable choice for achieving accurate crossover filtering in high-fidelity speaker systems.
