Jantzen Audio 000-5045 | 4,5 mH | 0,47 Ω | 3% | 18 AWG

The Jantzen Audio 000-5045 iron core coil with discs is a premium component designed to elevate the performance of high-fidelity loudspeaker systems. This 4.5 mH inductor is engineered to deliver precise and reliable crossover filtering, ensuring that each driver in your speaker operates within its optimal frequency range for a cohesive and natural soundstage. Its robust construction makes it an ideal choice for both DIY audio enthusiasts and professional loudspeaker designers seeking consistent, high-quality results.

This coil excels in demanding audio applications, particularly in passive crossover networks for two-way and three-way speaker designs. It is perfectly suited for use in bass and midrange filtering, where its iron core construction provides high inductance values in a compact form factor. Whether you are building custom studio monitors, upgrading existing home theatre speakers, or crafting bespoke hi-fi systems, this component offers the stability and performance required for critical listening environments.

Technically, the coil features a 4.5 mH inductance with a tight ±3% tolerance, guaranteeing consistent performance across production batches. The 18 AWG (1.02 mm diameter) copper wire winding results in a low DC resistance of just 0.47 Ω, minimising signal loss and power dissipation. The iron core is encased with protective discs, and the overall dimensions of 40 x 46 mm allow for straightforward integration into most crossover boards. This combination of precision and low resistance ensures clean, undistorted signal transfer.

In summary, the Jantzen Audio 000-5045 iron core coil is a reliable and high-performing component for any serious loudspeaker project. Its precise specifications and robust build quality make it a worthy investment for achieving accurate and enjoyable sound reproduction.
