Rated for 2.7 A continuous with a saturation current of 3.3 A (Isat) — the 3.3 A ceiling means the inductance holds flat up to that current before rolling off, so a power rail pulling 2.5 A still sees the full 1 µH. ## DCR and saturation — the so-what for a power rail Maximum DC resistance is 60 mOhm — at 2.7 A the I²R loss is 437 mW, which the 0805 body dissipates into the board copper; the metal core helps pull heat out through the pads. The 3.3 A saturation current (Isat) is the point where inductance drops by roughly 30 % — for a buck converter output filter, keep the peak inductor current below 3.3 A to avoid ripple-current runaway.","metaTitle":"Murata DFE21CCN1R0MELL 1 µH Shielded Inductor, 2.7 A","metaDescription":"Murata DFE21CCN1R0MELL drum core wirewound inductor, 1 µH ±20%, shielded, 2.7 A rated, 60 mOhm DCR max, 0805 package.
