Jantzen Audio 000-7852 | 1,33 mH | 0,43 Ω | 2% | 16 AWG

The Jantzen Audio 000-7852 Cross Foil Coil is a premium-grade copper foil inductor designed for audiophiles and loudspeaker builders who demand uncompromising signal purity. With an inductance of 1.33 mH and an exceptionally low DC resistance of just 0.43 Ω, this component ensures minimal energy loss and superior transient response in crossover networks. Its ±2% tolerance guarantees consistent, repeatable performance across production batches, making it an ideal choice for high-fidelity loudspeaker designs where precision is paramount.

This foil coil excels in passive crossover circuits for two-way and three-way speaker systems, particularly in applications requiring low insertion loss and stable phase behaviour. It is also well-suited for use in tube amplifiers and high-end audio projects where maintaining signal integrity is critical. The 16 AWG equivalent cross-section and copper foil winding reduce skin effect and eddy current losses, delivering a cleaner, more natural sound compared to conventional wire-wound inductors.

Technically, the coil measures 71 x 27 mm and features a robust cross-foil construction that minimises parasitic capacitance and electromagnetic interference. The foil winding provides a larger surface area for current flow, reducing resistance and improving thermal handling. Each unit is individually tested to ensure the stated inductance and tolerance are met, offering reliable performance in demanding audio applications.

Whether you are upgrading an existing crossover or building a new reference system, this Jantzen Audio foil coil delivers the transparency and detail that discerning listeners expect.
