Jantzen Audio 000-2409 | 0,22 mH | 0,17 Ω | 3% | 21 AWG

The Jantzen Audio 000-2409 iron core coil is a precision component designed to elevate the performance of high-fidelity loudspeaker systems. As part of Jantzen’s respected range, this coil offers reliable and consistent inductive behaviour, making it an essential building block for audiophile-grade crossover networks. Whether you are constructing a new pair of speakers or upgrading an existing design, this component helps ensure accurate frequency division between drivers.

This 0.22 mH coil is ideally suited for use in low-pass and band-pass filter sections, particularly where a compact, high-inductance solution is required. Its iron core construction allows for a physically smaller coil compared to air core alternatives at the same inductance, making it a practical choice for space-constrained enclosures. Typical applications include crossover networks for woofers and midrange drivers, where controlled inductance and low DC resistance are critical for maintaining sound quality and efficiency.

Technically, the coil features a DC resistance of just 0.17 Ω, minimising power loss and heat generation. The winding uses 21 AWG wire with a diameter of 0.72 mm, and the inductance is held to a tight ±3% tolerance, ensuring consistent performance from unit to unit. The core is of the iron type, and the overall dimensions are 17 x 30 mm, allowing for straightforward integration into most crossover boards.

In summary, the Jantzen Audio 000-2409 iron core coil delivers precise, reliable performance for demanding loudspeaker crossover applications, combining compact size with excellent electrical characteristics.
