Jantzen Audio 000-0272 | 1,4 mH | 0,60 Ω | 3% | 18 AWG

The Jantzen Audio 000-0272 air core coil is a premium component designed for discerning audio enthusiasts and professional speaker builders. This 1.4 mH inductor delivers exceptional performance in crossover networks, ensuring precise frequency filtering for high-fidelity sound reproduction. Its air core construction eliminates core saturation and distortion, making it ideal for audiophile-grade loudspeaker designs where signal purity is paramount.

This coil is perfectly suited for use in passive crossover circuits, particularly in midrange and tweeter applications where low-loss performance is critical. Whether you are upgrading existing speakers or building custom designs from scratch, this component provides the accuracy needed to achieve seamless driver integration and balanced tonal response. Its compact dimensions (55 x 15 mm) allow for flexible placement within enclosures.

Technically, the coil features a 1.4 mH inductance with a tight ±3% tolerance, ensuring consistent performance across production batches. The 18 AWG (1.02 mm diameter) wire offers a low DC resistance of 0.60 Ω, minimising power loss and heat generation. As an air core design, it avoids the hysteresis and non-linearities associated with ferrite or iron cores, preserving transient response and detail. The robust construction ensures long-term reliability in demanding audio systems.

For your next high-fidelity project, this Jantzen Audio air core coil delivers the precision and sonic transparency that serious builders demand.
