Jantzen Audio 000-1990 | 0,56 mH | 0,39 Ω | 3% | 18 AWG

The Jantzen Audio 000-1990 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 with minimal interference, making it an essential part of any serious crossover network.

This 0.56 mH inductor is ideally suited for use in passive crossover filters, where it helps to precisely divide the audio frequency spectrum between drivers such as woofers, midranges, and tweeters. Its air core construction eliminates the core saturation and hysteresis distortion often associated with iron-core alternatives, resulting in cleaner, more transparent sound reproduction. Whether you are building custom speakers or upgrading existing designs, this coil delivers consistent, reliable performance.

Constructed with 18 AWG wire and a diameter of 1.02 mm, the coil offers a low DC resistance of just 0.39 Ω, ensuring minimal power loss and excellent signal integrity. The inductance tolerance of ±3% guarantees precise crossover points, while the compact dimensions of 33 x 25 mm allow for easy integration into tight enclosures. As a true air core design, it provides linear performance across a wide frequency range, making it a trusted choice for discerning audio projects.
