Jantzen Audio 000-5012 | 3,0 mH | 0,19 Ω | 3% | 15 AWG

The Jantzen Audio 000-5012 iron core coil with discs is a premium component designed for audiophile-grade loudspeaker crossover networks. Its robust construction and precise electrical characteristics make it an ideal choice for demanding audio enthusiasts and professional speaker builders seeking accurate frequency filtering with minimal signal degradation.

This 3.0 mH inductor excels in low-frequency crossover applications, particularly for woofers and subwoofers where high inductance values are required. The iron core construction allows for a compact form factor while maintaining excellent magnetic efficiency, making it suitable for both new speaker designs and upgrades to existing systems. The integrated discs help manage eddy currents and reduce distortion, ensuring clean bass reproduction.

Technically, this coil features a low DC resistance of just 0.19 Ω, which minimises power loss and preserves amplifier damping factor for tight, controlled bass. The inductance is rated at 3.0 mH with a tight ±3% tolerance, ensuring consistent performance across production batches. Wound with 15 AWG (1.45 mm diameter) wire, it offers a good balance between current handling and physical size, with overall dimensions of 47 x 46 mm. The iron core with discs construction further enhances linearity and reduces core saturation at higher power levels.

For your next high-fidelity speaker project, this Jantzen Audio coil delivers the precision and sonic transparency required to achieve accurate crossover slopes and natural sound reproduction.
