Designed for output filtering and power-choke duties in DC-DC converters, the F1A1-383812/383815/383818 Series covers a broad inductance and current range in a shielded surface-mount body. Three height variants, 1.2 mm, 1.5 mm, and 1.8 mm, share a 3.8 × 3.8 mm footprint, giving designers a profile choice without changing the PCB land pattern. Shielded construction reduces EMI in automotive, industrial, and commercial power supply applications.
