Jantzen Audio 000-5170 | 4,0 mH | 0,285 Ω | 3% | 17 AWG

The Jantzen Audio 000-5170 iron core coil with discs is a high-quality component engineered for demanding loudspeaker crossover networks. As part of Jantzen’s renowned range, this coil delivers reliable performance and consistent results for audio enthusiasts and professional designers alike.

This 4.0 mH inductor is ideally suited for low-pass filter sections in multi-way speaker systems, where precise control of the bass and midrange frequencies is essential. Its robust iron core construction makes it particularly effective for handling higher power levels without saturation, ensuring clean and accurate sound reproduction even at elevated volumes. Whether you are building a new pair of speakers or upgrading an existing design, this coil provides the stability and linearity required for critical audio applications.

Technically, the coil features a low DC resistance of just 0.285 Ω, which minimises signal loss and preserves the amplifier’s damping factor for tighter bass response. The inductance value is held to a tight ±3% tolerance, guaranteeing consistent performance across production batches. Wound with 17 AWG (1.15 mm diameter) wire, it offers an excellent balance between current handling and compact dimensions. The overall size of 45 x 46 mm allows for straightforward integration into most crossover boards.

With its precise specifications and Jantzen Audio’s reputation for quality, this iron core coil is a dependable choice for achieving accurate crossover filtering in high-fidelity loudspeaker projects.
