Jantzen Audio 000-5477 | 4,7 mH | 0,405 Ω | 3% | 18 AWG

The Jantzen Audio 000-5477 iron core coil with discs is a premium component engineered for high-fidelity loudspeaker crossover networks. This 4.7 mH inductor delivers exceptional stability and accuracy, making it an ideal choice for audiophiles and DIY speaker builders who demand precise frequency filtering in their designs.

This coil excels in passive crossover applications, particularly for low-pass filters in two-way or three-way speaker systems. Its robust iron core construction ensures consistent performance across a wide frequency range, while the integrated discs minimise mechanical hum and vibration. Whether you are upgrading an existing speaker or building a custom enclosure, this component provides the reliability needed for critical audio paths.

Technically, the coil features an inductance of 4.7 mH with a tight ±3% tolerance, ensuring predictable crossover behaviour. The 18 AWG copper wire offers a low DC resistance of just 0.405 Ω, reducing power loss and maintaining signal integrity. Measuring 35 x 45 mm, the compact design fits neatly into most crossover boards. The iron core with discs enhances magnetic flux concentration while reducing eddy current losses, contributing to cleaner sound reproduction.

In summary, the Jantzen Audio 000-5477 iron core coil combines precise specifications with robust construction, making it a dependable choice for achieving accurate crossover performance in high-quality speaker systems.
