Jantzen Audio 000-2175 | 0,47 mH | 0,126 Ω | 3% | 18 AWG

The Jantzen Audio 000-2175 iron core coil is a premium component designed to deliver accurate and reliable performance in loudspeaker crossover networks. As part of Jantzen’s respected range, this coil is engineered to meet the demands of both DIY audio enthusiasts and professional speaker builders seeking high-quality sound reproduction.

This 0.47 mH inductor is ideally suited for low-frequency crossover applications, where precise filtering is essential to achieve a clean and natural bass response. Its iron core construction ensures high inductance values in a compact form, making it a practical choice for two-way and multi-way speaker systems where space is at a premium. Whether you are upgrading an existing design or building a new pair of speakers, this coil helps maintain signal integrity and minimise distortion.

Technically, the coil features a DC resistance of just 0.126 Ω, which contributes to efficient power handling and reduced signal loss. The winding uses 18 AWG wire with a diameter of 1.02 mm, and the inductance tolerance is held to ±3% for consistent performance. Measuring 18 x 40 mm, the coil is built with a robust iron core that enhances magnetic flux while keeping the overall size manageable. Each unit is carefully manufactured to Jantzen’s exacting standards, ensuring long-term reliability.

In summary, the Jantzen Audio 0.47 mH iron core coil offers a precise, low-loss solution for crossover design, combining technical accuracy with practical build quality for superior audio results.
