The metal-alloy composite core keeps core loss low in the 1–3 MHz switching range common to automotive point-of-load converters. ## Current Handling and Saturation Margin The 1.8 A current rating is the DC bias current at which the temperature rise from self-heating stays within the component's design limit. The 2.1 A saturation current (Isat) is the point where inductance typically drops 30% — the real-world design margin is the gap between the load's peak current and Isat, not the 1.8 A rating. Max DCR of 109 mOhm sets the I²R conduction loss: at 1.8 A the resistive loss is 353 mW, which drives the temperature rise. The 150°C absolute max operating temperature means the sum of ambient + self-heating must stay under that ceiling; a 125°C ambient leaves only 25°C of headroom for the inductor's own temperature rise. ## 0806 Footprint and Board Integration The 0806 case (2.00 x 1.60 mm) with 1.20 mm seated height fits tight power-stage layouts where a taller 1210 or 1275 inductor would interfere with an adjacent heatsink or cover. The shielded construction contains the magnetic flux within the ferrite/metal composite body — adjacent traces carrying sensitive analog signals see less EMI coupling than an unshielded drum core. Surface-mount termination in tape-and-reel packaging supports standard pick-and-place assembly. The base product number DFE2MCAH identifies the 1.5 µH variant in the DFE2M family; tolerance is ±20% per, which is typical for power-grade inductors where the DC-DC loop compensates for the inductance spread.","metaTitle":"Murata DFE2MCAH1R5MJ0L Shielded Power Inductor, 1.5 µH","metaDescription":"Murata DFE2MCAH1R5MJ0L wirewound drum core inductor, 1.5 µH ±20%, 1.8 A, shielded, AEC-Q200, 0806 package.
