Intertechnik E170/270/300 | 2.7 mH | 0.18 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core Inductor, model E170, offers a precise 2.70 mH inductance that is ideal for audiophile-grade loudspeaker crossover networks. Its air-core design eliminates the risk of core saturation, ensuring linear and distortion-free performance even at higher signal levels. This makes it particularly well-suited for high-fidelity audio systems where clarity and accuracy are paramount, such as in home theatre setups, studio monitors, or custom-built speaker enclosures. The inductor’s robust construction supports reliable operation in passive crossover circuits, helping to achieve clean frequency separation between drivers.

Technically, this component features a low DC resistance of just 0.18 Ω, wound with 3.00 mm diameter copper wire to minimise power loss and handle up to 40 watts of continuous power. The inductance tolerance is ±3.0%, providing consistent and predictable filtering. For mounting, it includes four fixing holes with a 4.2 mm diameter, and the overall depth measures 37 mm, allowing straightforward integration into your design. Whether you are upgrading an existing system or building from scratch, this air-core inductor delivers the performance and reliability expected from Intertechnik.
