Jantzen Audio 000-1040 | 0,56 mH | 0,61 Ω | 3% | 21 AWG

The Jantzen Audio 000-1040 air core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As a premium choice for audio enthusiasts and professional designers alike, this coil ensures accurate signal handling and minimal distortion, making it an essential building block for custom crossover networks.

This 0.56 mH inductor is ideally suited for use in passive crossover circuits, where it facilitates precise frequency filtering to separate audio signals between tweeters, midrange drivers, and woofers. Its air core construction eliminates core saturation and hysteresis effects, delivering linear performance across a wide frequency range. Whether you are upgrading an existing speaker system or building a new design from scratch, this coil provides the reliability and consistency required for critical audio applications.

Technically, the coil features a 21 AWG wire diameter of 0.72 mm, with a DC resistance of just 0.61 Ω to minimise power loss. The inductance value is held to a tight ±3% tolerance, ensuring predictable behaviour in your circuit. With compact dimensions of 30 x 15 mm, it integrates easily into crossover boards without adding excessive bulk. The air core design also guarantees low eddy current losses, preserving signal purity and transient response.

For discerning audio projects where component quality directly influences sound reproduction, this Jantzen Audio air core coil offers a dependable solution that combines precision engineering with practical performance.
