Category
This magnetic component is designed for EMI filtering in DC-DC converters and RF modules, offering 0.5A continuous current handling with 12-48VDC operation. It requires soldering at ≤250°C and thermal management via copper planes. Applications include industrial motor drives and telecom base stations, with static discharge precautions. Alternative models should match inductance (20-100μH) and frequency (1-10MHz) parameters.
