Jantzen Audio 000-5245 | 4,5 mH | 0,39 Ω | 3% | 18 AWG

The Jantzen Audio 000-5245 iron core coil with discs is a premium component engineered for audiophile-grade loudspeaker crossover networks. Its robust construction and precise electrical characteristics make it an ideal choice for designers seeking accurate frequency filtering in high-fidelity systems, from bookshelf speakers to large floor-standing towers. This coil excels in low-frequency applications, where its iron core provides high inductance values in a compact form factor, ensuring deep, controlled bass response without excessive bulk.

Technically, this coil offers a 4.5 mH inductance with a tight ±3% tolerance, guaranteeing consistent performance across production batches. The low 0.39 Ω DC resistance minimises power loss and heat generation, preserving signal integrity even under demanding loads. Wound with 18 AWG (1.02 mm diameter) wire, it balances current handling with manageable size. The core features integrated discs to reduce stray magnetic fields and mechanical hum, while the 45 x 46 mm dimensions allow straightforward mounting. Finished with a durable coating, this Jantzen Audio coil delivers reliable, long-term performance in passive crossover designs, making it a trusted choice for both DIY enthusiasts and professional loudspeaker manufacturers.
