Intertechnik TRI55/018/0.50 | 0,18 mH | 0,13 Ω | 1% | 24 AWG

The Intertechnik TRI55/018/0.50 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.18 mH and a low DC resistance of just 0.13 Ω, this coil ensures minimal signal loss and accurate frequency filtering, making it ideal for high-fidelity audio systems where clarity and detail are paramount.

This coil is particularly well-suited for use in passive crossover designs, where it can be employed to separate midrange and tweeter frequencies with exceptional precision. Its tight ±1% tolerance guarantees consistent performance across multiple units, which is essential for stereo imaging and balanced sound reproduction. Whether you are building custom speakers or upgrading existing designs, this component delivers reliable and repeatable results.

Constructed with 24 AWG wire and a 0.5 mm wire diameter, the coil features a 55 mm outer diameter and a 28 mm core diameter, with a total height of 30 mm. The winding width of 23 mm and a central hole of 5.3 mm facilitate easy mounting and integration into crossover boards. The recessed diameter of 25.5 mm allows for secure placement, while the air core design eliminates core saturation and distortion, preserving signal purity across the entire audio bandwidth.

Combining robust build quality with precise electrical specifications, this Intertechnik air core coil is a trusted choice for discerning audio enthusiasts and professional designers alike.
