Jantzen Audio 000-5820 | 0,72 mH | 0,14 Ω | 3% | 18 AWG

The Jantzen Audio 000-5820 iron core coil with discs is a premium-grade component engineered for high-fidelity loudspeaker crossover networks. Designed to deliver accurate and stable filtering, this coil ensures that each driver in your speaker system receives precisely the correct frequency range, resulting in a coherent and natural soundstage. Its robust construction makes it an ideal choice for both DIY audio enthusiasts and professional loudspeaker manufacturers seeking reliable performance in demanding audio applications.

This coil is particularly well-suited for use in passive crossover designs, where it effectively manages low-frequency signals with minimal distortion. Whether you are building a new set of bookshelf speakers or upgrading an existing high-end system, the 000-5820 provides the precision and consistency required for critical audio reproduction. Its iron core construction offers high inductance values in a compact form factor, making it a practical solution for space-constrained enclosures.

Technically, the coil features an inductance of 0.72 mH with a tight tolerance of ±3%, ensuring consistent performance across units. The DC resistance is exceptionally low at 0.14 Ω, which minimises signal loss and preserves amplifier power. Wound with 18 AWG wire (1.02 mm diameter), it handles moderate current levels efficiently. The physical dimensions are 35 x 45 mm, and the iron core is encased with protective discs for durability and reduced mechanical noise.

In summary, the Jantzen Audio 000-5820 iron core coil combines precise electrical specifications with robust build quality, making it a reliable choice for achieving accurate crossover filtering in high-quality speaker designs.
