Product details
Jantzen Audio 000-5028 | 7,4 mH | 0,79 Ω | 3% | 20 AWG | Iron Core Coil with Discs
The Jantzen Audio 000-5028 iron core coil is an essential component for audiophiles looking to build or upgrade their speaker crossovers, particularly for the bass and mid-sections. Its 7.4mH inductance value is achieved with a high level of precision, evidenced by a 3% tolerance, ensuring accurate crossover frequencies. The coil's low direct current resistance (DCR) of just 0.79 ohms means minimal impact on the driver's damping factor and efficiency, a critical factor for maintaining sound quality.
Wound with high-purity 20 AWG copper wire around a Permite core supplemented with discs, this coil offers remarkable conductivity and energy efficiency. The selected non-ferrite core material significantly reduces hysteresis losses compared to traditional ferrite cores, thereby enhancing the coil's power handling capability without compromising on fidelity. The coil's design is optimized for use in the lower frequency ranges, making it an ideal choice for the bass and mid sections of a crossover network. The combination of a robust Permite core with carefully chosen wire thickness ensures that the coil can handle the power necessary for these demanding applications while maintaining a compact form factor.
