Jantzen Audio 000-1203 | 0,49 mH | 0,325 Ω | 3% | 18 AWG

The Jantzen Audio 000-1203 air core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. This 0.49 mH inductor delivers precise crossover filtering, ensuring that each driver in your speaker operates within its optimal frequency range for a clean, natural sound reproduction.

Ideal for audiophile-grade speaker builds, crossover network upgrades, and DIY audio projects, this coil excels in applications where signal purity and minimal distortion are paramount. Its air core design eliminates core saturation and hysteresis losses, making it particularly suitable for high-power handling and critical listening environments. Whether you are designing a two-way bookshelf speaker or a complex multi-driver system, this inductor provides the accuracy needed for seamless driver integration.

Constructed with 18 AWG wire, the coil features a low DC resistance of just 0.325 Ω, which minimises power loss and maintains signal integrity. The ±3% tolerance ensures consistent performance across production batches, while the compact dimensions of 40 x 15 mm allow for easy integration into tight crossover layouts. The air core construction further guarantees stable inductance values regardless of current levels, delivering reliable and repeatable results.

With its robust build and precise specifications, the Jantzen Audio 0.49 mH air core coil is a trustworthy choice for any serious loudspeaker project, offering both sonic transparency and long-term dependability.
