Jantzen Audio 000-2303 | 1,0 mH | 0,29 Ω | 3% | 20 AWG

The Jantzen Audio 000-2303 iron core coil is a high-quality component designed to elevate the performance of your loudspeaker systems. Engineered for precision, this 1.0 mH inductor ensures accurate crossover filtering, allowing you to achieve a clean and balanced sound reproduction that audiophiles and DIY enthusiasts will appreciate.

This coil is ideally suited for use in passive crossover networks within hi-fi speakers, studio monitors, and custom audio projects. Its robust construction makes it a reliable choice for both new builds and upgrades, where consistent inductance and low resistance are critical for maintaining signal integrity and minimising power loss.

Technically, the coil features a 1.0 mH inductance with a tight ±3% tolerance, ensuring dependable performance across production batches. The DC resistance is a low 0.29 Ω, which helps preserve amplifier damping factor and reduces energy dissipation. Wound with 20 AWG (0.81 mm diameter) wire on an iron core, it offers a compact footprint of 19 x 40 mm, making it easy to integrate into crowded crossover boards. The iron core construction provides high inductance values in a smaller package compared to air core alternatives, while the precise winding guarantees stable electrical characteristics.

For your next speaker project, this Jantzen Audio coil delivers the accuracy and reliability needed for superior sound quality.
