COT92/4.7/14 | 4,7 mH | 0,55 Ω | 5% | 15 AWG | Corotherm Coil

The Intertechnik Corotherm heat-resistant coil delivers exceptional performance for demanding audio applications, offering a robust 4.70 mH inductance that ensures precise crossover filtering in high-power speaker systems. This iron core coil is ideally suited for use in professional loudspeaker designs, home theatre setups, and high-fidelity audio installations where thermal stability and consistent electrical characteristics are paramount. Its construction allows it to handle elevated temperatures without degradation, making it a reliable choice for continuous high-output operation.

Technically, the coil features a DC resistance of just 0.55 Ω, minimising power loss and maintaining signal integrity. The winding utilises 1.32 mm diameter copper wire, which provides excellent current handling and low resistive losses. With an outer diameter of 92 mm, a core diameter of 30 mm, and a total height of 39 mm, this component is designed for straightforward integration into crossover networks. The central hole measures 5 mm, while the recess diameter is 25.5 mm, and the winding width is 33 mm. The inductance tolerance is ±5.0%, ensuring accurate and repeatable filtering. This Corotherm coil combines thermal resilience with precise electrical specifications, offering a durable solution for audiophiles and engineers seeking uncompromising sound quality.
