Intertechnik COT92/8.2/14 | 8.2 mH | 0.80 Ω | 5% | 15 AWG | Corotherm Coil

The Intertechnik Corotherm heat-resistant coil delivers exceptional stability and reliability for demanding loudspeaker crossover networks. Engineered for high-power audio systems, this iron core inductor ensures consistent performance even under thermal stress, making it an ideal choice for audiophiles and professional speaker builders who require precise frequency division without degradation over time.

This 8.20 mH coil is perfectly suited for use in bass and midrange crossover circuits where maintaining accurate inductance is critical. Its robust construction allows it to handle elevated operating temperatures, preventing core saturation and preserving sound quality in high-output applications such as PA systems, home theatre setups, and custom speaker designs. The ±5% tolerance guarantees repeatable results across production runs.

Technical specifications include a DC resistance of 0.80 Ω, achieved with a 1.32 mm copper wire diameter that balances low loss with efficient current handling. The coil measures 92 mm in outer diameter, with a 30 mm core diameter and a total height of 39 mm. A 5 mm central bore and 25.5 mm recess diameter facilitate straightforward mounting. The winding width of 33 mm contributes to its thermal resilience and consistent electrical characteristics.

With its heat-resistant design and precise electrical parameters, the Intertechnik Corotherm coil is a dependable component for building or upgrading high-fidelity loudspeaker crossovers that must perform reliably under sustained high-power conditions.
