Intertechnik TRI62/039/0.60 | 0,39 mH | 0,16 Ω | 1% | 23 AWG

The Intertechnik TRI62/039/0.60 air core coil is a precision component engineered for discerning audio enthusiasts and professional loudspeaker designers. This 0.39 mH inductor delivers accurate crossover filtering, ensuring clean signal separation between drivers for a natural, uncoloured soundstage. Its air core construction eliminates core saturation and hysteresis distortion, making it ideal for high-fidelity systems where transparency and detail are paramount.

This coil excels in passive crossover networks for two-way and three-way speaker designs, particularly in audiophile-grade monitors, home cinema systems, and custom DIY projects. The low DC resistance of 0.16 Ω minimises power loss and maintains damping factor integrity, while the ±1% tolerance guarantees consistent performance across production batches. Wound with 23 AWG wire, the coil handles moderate power levels without overheating, suiting both bookshelf and floorstanding speakers.

Technical features include a 62 mm outer diameter, 28 mm core diameter, and a total height of 41 mm, with a winding width of 23 mm. The recessed diameter of 25.5 mm and central hole of 5.3 mm facilitate secure mounting on crossover boards. The compact 41 x 16 mm footprint allows flexible placement within enclosures. Manufactured by Intertechnik, this air core roll offers reliable, long-term stability for critical audio applications.
