Jantzen Audio 000-1645 | 0,25 mH | 0,38 Ω | 3% | 21 AWG

The Jantza Audio 000-1645 air core coil is a meticulously engineered component designed to elevate the performance of your loudspeaker crossover networks. Crafted with precision, this 0.25 mH inductor delivers clean, transparent signal handling, making it an ideal choice for audiophiles and DIY enthusiasts seeking to refine their sound systems.

This coil excels in high-fidelity audio applications, particularly within passive crossover circuits where accurate frequency division is paramount. Whether you are building custom speakers, upgrading existing designs, or restoring vintage audio equipment, its stable inductance ensures precise filtering, allowing tweeters and woofers to operate within their optimal ranges. The low 0.38 Ω DC resistance minimises power loss, preserving amplifier efficiency and dynamic response.

Technically, the coil features a 21 AWG wire diameter of 0.72 mm, wound on an air core to eliminate core saturation and hysteresis distortion. With a tight ±3% tolerance, it guarantees consistent performance across production batches. The compact dimensions of 31 x 8 mm facilitate easy integration into tight enclosures, while the air core design ensures linearity across a wide frequency spectrum. This combination of low resistance, precise inductance, and minimal distortion makes it a reliable foundation for critical audio paths.

In summary, the Jantzen Audio 000-1645 air core coil offers a perfect balance of accuracy, low loss, and compact form, delivering stable and distortion-free performance for discerning speaker projects.
