The 1210 footprint (3.20 x 2.50 mm body, 2.00 mm seated height) matches the standard inductor land pattern for this package class — no footprint deviation needed for pick-and-place reels.","metaTitle":"Murata DFE322520F-2R2M=P2 Shielded Power Inductor, 2.2 µH","metaDescription":"Active Murata DFE322520F-2R2M=P2 wirewound shielded inductor, 2.2 µH ±20%, 3.3 A, 40 mOhm DCR, 1210 package.

For a 2.2 µH shielded inductor with similar current handling, the standard DFE322520F-2R2M (without the =P2 suffix) is the base order code — the =P2 suffix typically denotes a specific packaging or customer-specific code variant.
