Intertechnik CO30/1.00/071 | 1,0 mH | 0,51 Ω | 5% | 21 AWG

The Intertechnik CO30/1.00/071 iron core choke coil is a precision component engineered to enhance the performance of loudspeaker crossover networks. By effectively reducing distortion in low-frequency filtering, this coil ensures cleaner, more accurate bass reproduction, making it an essential upgrade for audiophiles and DIY speaker builders seeking superior sound quality.

Ideal for use in two-way and three-way crossover designs, this choke coil excels at handling the demands of woofer and mid-bass drivers. Its robust construction allows it to manage higher currents without saturation, ensuring consistent performance even at elevated listening levels. Whether you are building a new set of speakers or refining an existing system, this component delivers reliable, long-lasting results.

Technically, the coil offers a 1.0 mH inductance with a DC resistance of just 0.51 Ω, minimising signal loss and heat generation. The ±5% tolerance ensures precise filtering, while the 21 AWG wire diameter and 0.71 mm wire gauge contribute to efficient current handling. The iron core design, with a 30 mm outer diameter and 19 mm core diameter, provides a compact yet powerful solution for crossover circuits. The 22 mm total height and 17.5 mm winding width allow for easy integration into most enclosures.

With its combination of low resistance, high inductance accuracy, and robust build, the Intertechnik CO30/1.00/071 is a dependable choice for achieving clean, distortion-free low-frequency performance in any high-fidelity audio system.
