Intertechnik FE130/220/20 | 22 mH | 0,37 Ω | 5% | 12 AWG

The Intertechnik Transformer Coil, rated at 22 mH and identified by the model FE130, represents a high-quality component for discerning audio enthusiasts and professional loudspeaker designers. This precision-wound coil is engineered to deliver accurate crossover filtering, ensuring that each driver in a multi-way speaker system receives only the frequencies it is designed to handle, thereby preserving the integrity of the original audio signal.

Ideal for use in passive crossover networks, this coil is particularly suited to high-fidelity home audio systems, studio monitors, and custom speaker builds where component quality directly influences sound clarity. Its robust construction makes it a reliable choice for both new designs and upgrades to existing loudspeaker projects, helping to achieve a more transparent and balanced frequency response.

Technically, the coil offers an inductance of 22 mH with a tight tolerance of ±5.0%, ensuring consistent performance across production units. The low DC resistance of just 0.37 Ω minimises signal loss and power dissipation, while the 2.00 mm copper wire diameter contributes to excellent current handling and thermal stability. With an outer diameter of 13 mm and a recess diameter of 5.5 mm, it is compact enough for integration into most crossover boards. Manufactured by Intertechnik, a trusted name in audio components, this coil combines precision engineering with durable materials for long-term reliability.

Whether you are refining a high-end speaker system or building from scratch, this Intertechnik coil provides the accuracy and low-loss performance required for superior sound reproduction.
