Jantzen Audio 000-2135 | 0,45 mH | 0,22 Ω | 3% | 20 AWG

The Jantzen Audio 000-2135 iron core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As part of Jantzen’s respected range, this coil delivers reliable and consistent inductive performance, making it an essential building block for serious audio enthusiasts and professional designers alike.

This coil is ideally suited for use in passive crossover networks, where precise inductance values are critical for accurate frequency filtering. Whether you are constructing a new set of bookshelf speakers, upgrading an existing design, or restoring vintage audio equipment, the 000-2135 ensures clean signal division between drivers, contributing to a balanced and natural soundstage. Its robust construction also makes it suitable for other low-frequency applications where stable inductance is required.

Technically, the coil offers an inductance of 0.45 mH with a tight tolerance of ±3%, ensuring consistent performance across production batches. The DC resistance is a low 0.22 Ω, minimising signal loss and power dissipation. Wound with 20 AWG wire (0.81 mm diameter), it handles moderate current levels efficiently. The iron core design provides high inductance in a compact form factor, with dimensions of 21 x 30 mm, allowing for easy integration into crowded crossover boards.

In summary, the Jantzen Audio 000-2135 iron core coil combines precision engineering with practical design, offering a reliable solution for achieving accurate crossover filtering in your next audio project.
