Intertechnik I150/33/132 | 33 mH | 1.16 Ω | 5% | 16 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, with a substantial 33 mH inductance, is a precision component designed for demanding audio crossover networks. Its robust construction ensures reliable performance in high-fidelity loudspeaker systems, where accurate frequency division is critical for achieving a balanced and natural soundstage. This coil is particularly well-suited for low-pass filter sections in multi-way speaker designs, effectively managing the transition between woofers and midrange drivers.

Engineered with a 1.32 mm copper wire diameter, the coil offers a low direct current resistance (DCR) of just 1.16 Ω, minimising power loss and heat generation during operation. The iron-core construction provides a high inductance value in a compact form factor, with an outer diameter of 58 mm and a total height of 49 mm, making it easy to integrate into crossover boards. The central hole of 7.9 mm allows for secure mounting. With a tight tolerance of ±5.0%, this coil delivers consistent, repeatable performance, essential for maintaining the integrity of your crossover design. Whether you are building a new speaker system or upgrading an existing one, this Intertechnik rod coil offers the reliability and precision required for superior audio reproduction.
