Intertechnik E130/082/300 | 0.82 mH | 0.09 Ω | 3% | 9 AWG | Choke Coil

The Intertechnik Air-core coil, with an inductance of 0.82 mH and a direct current resistance of just 0.09 Ω, represents a premium choice for audiophiles and loudspeaker designers who demand uncompromising performance. This high-quality component is purpose-built for use in passive crossover networks, where precise frequency division is essential to achieving a natural, transparent soundstage. Whether you are constructing a set of bookshelf speakers, a multi-way floor-standing system, or a dedicated studio monitor, this coil ensures that each driver receives only the frequencies it is designed to handle, minimising distortion and phase shift.

Technically, the coil is wound with 3.00 mm diameter copper wire, which contributes to its exceptionally low resistance and high current handling capability. The air-core design eliminates the risk of core saturation, preserving linearity even at high power levels. With a tolerance of ±3.0%, this component guarantees consistent performance across production batches. The overall dimensions are 49 x 46 mm, with a total height of 79 mm, making it suitable for compact crossover layouts. Finished with a robust E130 winding, this Intertechnik coil is a reliable foundation for any serious loudspeaker project, delivering the accuracy and transparency that discerning listeners value.
