Intertechnik I130/6.8/112 | 6.8 mH | 0.44 Ω | 5% | 17 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, rated at 6.80 mH, is a precision component engineered for demanding loudspeaker crossover networks. Its robust iron-core construction ensures reliable performance in both passive and active filter designs, making it an ideal choice for audiophiles and professional speaker builders seeking accurate frequency division and minimal signal degradation.

This coil excels in high-power applications where consistent inductance and low DC resistance are critical. It is particularly well-suited for low-pass filters in woofers and subwoofers, where its 0.44 Ω DCR minimises power loss and heat buildup. The ±5.0% tolerance guarantees tight matching between channels, essential for maintaining stereo imaging and phase coherence in multi-way speaker systems.

Technically, the coil features a 1.12 mm copper wire diameter, which reduces resistive losses and supports higher current handling. Its external diameter of 46 mm and total height of 39 mm allow for compact integration into crossover boards, while the 6.7 mm centre hole facilitates secure mounting. The iron-core design provides high inductance per turn, enabling a more compact footprint compared to air-core alternatives without sacrificing linearity.

In summary, this Intertechnik rod coil delivers dependable, high-fidelity performance for critical crossover applications. Its precise electrical specifications and robust build quality make it a trusted component for achieving accurate, transparent sound reproduction in bespoke speaker designs.
