Category
This magnetic component is a RoHS-compliant inductor/transformer designed for power supply filtering and EMI suppression. It operates within 12-48V DC with 0.5A continuous current, requiring soldering at 280-300°C and 3-5 seconds contact time. Key applications include renewable energy systems and wireless charging modules, but engineers must maintain 5mm clearance from high-frequency components and verify compatibility with 2-4A DC/DC converters. Storage requires anti-static bags at controlled humidity, while thermal management needs 0.5mm FR4 PCB pads. Market positioning highlights competitive pricing and EU market compliance, though limited stock and lack of extreme temperature testing remain considerations.
