Intertechnik E170/300/300 | 3.0 mH | 0.19 Ω | 3% | 9 AWG | Choke Coil

This Intertechnik air-core inductor, with a precise 3.00 mH inductance, is an essential component for audiophiles and speaker builders seeking accurate crossover filtering. Its design ensures minimal signal degradation, making it ideal for high-fidelity audio systems where clarity and detail are paramount. Whether you are constructing custom loudspeakers, upgrading existing crossovers, or repairing vintage audio equipment, this inductor delivers reliable performance.

The inductor is particularly suited for use in passive crossover networks, where it helps to separate frequency bands with precision. Its low DC resistance of just 0.19 Ω reduces power loss and heat generation, preserving the integrity of the audio signal. This makes it an excellent choice for both mid-range and bass drivers, where efficient energy transfer is critical.

Technically, the inductor features a 3.00 mm copper wire diameter, which contributes to its low resistance and high current handling capacity. The ±3.0% tolerance ensures consistent performance across units, while the air-core construction eliminates core saturation and distortion, even at high power levels. This robust design guarantees long-term stability and sonic purity.

In summary, this Intertechnik air-core inductor combines precision engineering with practical performance, making it a reliable choice for demanding audio projects. Its technical specifications ensure minimal signal loss and accurate crossover behaviour, enhancing the overall sound quality of your speaker system.
