Jantzen Audio 000-2218 | 0,39 mH | 0,20 Ω | 3% | 20 AWG

The Jantzen Audio 0.39 mH iron core coil is a premium-grade component designed to elevate the performance of your loudspeaker crossover networks. Manufactured to exacting standards, this inductor ensures accurate signal filtering, allowing you to achieve a clean and balanced sound reproduction in your audio projects.

Ideal for use in high-fidelity speaker systems, this coil excels in low-frequency crossover applications where its iron core construction provides high inductance values in a compact form factor. Whether you are building custom loudspeakers, repairing vintage audio equipment, or upgrading existing designs, this inductor delivers consistent and reliable performance. It is particularly well-suited for bass and midrange drivers, where precise filtering is critical to maintaining tonal accuracy and minimising distortion.

Technically, the coil offers an inductance of 0.39 mH with a tight tolerance of ±3%, ensuring minimal variation between units for predictable results. The DC resistance is a low 0.20 Ω, which helps preserve amplifier power and reduce signal loss. Wound with 20 AWG wire (0.81 mm diameter), it handles moderate current levels efficiently. The iron core design maximises inductance per turn, while the compact dimensions of 21 x 30 mm allow for easy integration into crossover boards.

With its robust build and precise specifications, this Jantzen Audio coil is a reliable choice for discerning audio enthusiasts and professionals seeking consistent crossover performance.
