The F1A2-3838 is a shielded surface-mount power inductor with heights from 1.2 mm to 1.8 mm over a 3.8 × 3.8 mm footprint, covering a broad inductance range for output filtering, energy storage, and noise suppression in DC-DC converters. Shielded construction limits EMI, and three height variants share a common land pattern for design reuse in automotive, commercial, and industrial applications.
