Intertechnik FE130/330/20 | 33 mH | 0.48 Ω | 5% | 12 AWG | Transformer Core Coil

The Intertechnik Transformer Coil, with an inductance of 33 mH and a part number FE130, represents a premium choice for audio enthusiasts and professional speaker builders seeking precise crossover network performance. This high-quality component is specifically engineered for use in passive crossover designs, where accurate filtering is essential to achieve seamless driver integration and optimal sound reproduction. Whether you are constructing a new set of loudspeakers or upgrading an existing system, this coil ensures that frequencies are directed correctly to the appropriate drivers, minimising distortion and enhancing overall clarity.

From a technical standpoint, this coil offers a direct current resistance (DCR) of just 0.48 Ω, which helps maintain signal integrity and reduces power loss within the circuit. The wire diameter of 2.00 mm, constructed from high-purity copper, ensures excellent current handling and low heat generation during operation. With an external diameter of 13 mm and a recess diameter of 5.5 mm, the coil is compact yet robust, allowing for straightforward integration into most crossover boards. The inductance tolerance of ±5.0% guarantees consistent performance across production batches, making this Intertechnik coil a reliable foundation for any high-fidelity audio project.
