Jantzen Audio 000-0103 | 0,12 mH | 0,06 Ω | 3% | 13 AWG

The Jantzen Audio 000-0103 air core coil is a precision component designed for audiophiles and speaker builders who demand uncompromising signal purity. With its 0.12 mH inductance and exceptionally low 0.06 Ω DC resistance, this coil ensures minimal power loss and distortion, making it an ideal choice for high-fidelity crossover networks. Its air core construction eliminates core saturation and hysteresis effects, preserving the natural timbre and transient response of your loudspeaker drivers.

This coil excels in crossover applications for two-way and three-way speaker systems, particularly where precise filtering is critical for seamless driver integration. It is equally suited for DIY projects, repair work, or upgrading existing designs, offering reliable performance in both passive and active crossover topologies. The ±3% tolerance guarantees consistent results across multiple units, essential for matched pairs or production runs.

Technically, the coil is wound with 13 AWG (1.83 mm diameter) wire, providing robust current handling and low resistive losses. Its dimensions of 40 x 25 mm make it compact enough for tight enclosures while maintaining excellent thermal stability. The air core design ensures linear inductance across the audio frequency range, delivering clean, uncoloured sound reproduction.

Backed by Jantzen Audio’s reputation for quality, this coil is a dependable choice for achieving accurate crossover slopes and superior audio performance in any speaker project.
