Jantzen Audio 000-1421 | 0,18 mH | 0,43 Ω | 3% | 21 AWG

The Jantzen Audio 000-1421 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Manufactured to exacting standards, this 0.18 mH inductor ensures accurate signal filtering, preserving the integrity of your audio system. Its air core construction eliminates core saturation and hysteresis distortion, delivering clean, transparent sound reproduction.

This coil is ideally suited for use in high-fidelity speaker designs, particularly for tweeter and midrange crossover circuits where low loss and minimal signal degradation are paramount. It is also an excellent choice for DIY audio enthusiasts and professional speaker builders seeking to upgrade or customise existing crossover networks. The compact dimensions of 29 x 30 mm allow for easy integration into tight enclosures without compromising performance.

Technically, the coil features a 21 AWG wire diameter of 0.72 mm, providing a DC resistance of just 0.43 Ω. This low resistance ensures efficient power handling and minimal energy loss. The inductance value of 0.18 mH is held to a tight ±3% tolerance, guaranteeing consistent performance across production batches. As a true air core design, it avoids the non-linearities associated with ferromagnetic cores, resulting in stable inductance over a wide frequency range.

Whether you are building a new speaker system or refining an existing one, this Jantzen Audio air core coil offers the reliability and sonic purity required for critical audio applications.
