Jantzen Audio 000-5420 | 1,35 mH | 0,21 Ω | 3% | 18 AWG

The Jantzen Audio 000-5420 iron core coil with discs is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. This 1.35 mH inductor is an ideal choice for audiophiles and DIY enthusiasts seeking precise crossover filtering, ensuring that each driver in a multi-way speaker receives only the frequencies it is intended to handle. Its robust construction makes it particularly suitable for use in bass and midrange circuits, where maintaining signal integrity is paramount.

Technically, this coil features a low DC resistance of just 0.21 Ω, which minimises power loss and preserves the amplifier's damping factor for tighter, more controlled bass response. The ±3% tolerance guarantees consistent performance across production runs, allowing for accurate crossover design. Wound with 18 AWG wire and built around a laminated iron core, it offers high inductance in a compact footprint measuring 27 x 38 mm. The integrated discs provide mechanical stability and help manage eddy currents, further reducing distortion. Whether you are upgrading an existing pair of speakers or building a new set from scratch, this Jantzen Audio coil delivers the reliability and sonic transparency required for critical listening applications.
