Jantzen Audio 000-1242 | 0,47 mH | 0,19 Ω | 3% | 15 AWG

The Jantzen Audio 000-1242 air core coil is a premium component designed for discerning audio enthusiasts and loudspeaker builders who demand uncompromising signal purity. This 0.47 mH inductor delivers precise crossover filtering, ensuring that each driver in your speaker system receives only the frequencies it was designed to handle, resulting in a clean, natural soundstage with minimal distortion.

Ideal for use in high-fidelity home audio systems, studio monitors, and custom DIY speaker projects, this coil excels in both two-way and three-way crossover networks. Its air core construction eliminates the core saturation and hysteresis distortion often found in iron-core alternatives, making it particularly suitable for critical listening environments where transparency and detail are paramount.

Technically, the coil features a 15 AWG wire diameter (1.45 mm) with a low DC resistance of just 0.19 Ω, minimising power loss and maintaining signal integrity. The inductance value of 0.47 mH is held to a tight ±3% tolerance, ensuring consistent performance across production batches. With compact dimensions of 60 x 15 mm, it integrates easily into most crossover boards. The air core design also guarantees stable inductance regardless of current level, preserving linearity even at high volumes.

For your next loudspeaker project, this Jantzen Audio coil offers the reliability and sonic accuracy required to achieve professional-grade results.
