The metal core's thermal conductivity helps pull heat into the PCB copper, so the actual temperature rise at full rated current depends on the board's copper pour and via density under the part. At the high end, the DCR increases with temperature per the copper temperature coefficient — the effective resistance at 125°C is roughly 1.4× the 25°C value, so the I²R loss at the same current rises accordingly. Budget this derating if the inductor runs near its thermal limit in a 105°C ambient. Shielded construction contains the magnetic flux within the core body, reducing radiated EMI coupling to nearby traces and sensitive analog circuits. This is relevant when the inductor sits close to a high-impedance sensor front-end or a wireless transceiver on the same board layer. ## 0806 footprint and board integration The low profile suits mezzanine cards and multi-layer boards where the component height on the secondary side is constrained by an enclosure or a second PCB stacked above. Surface-mount assembly with Tape & Reel or Cut Tape packaging — the reel quantity is the standard production feed; Cut Tape works for prototype or low-volume builds without a reel changeover on the pick-and-place line.","metaTitle":"Murata DFE201612P-R47M=P2 Shielded Power Inductor, 4.8 A","metaDescription":"Active Murata DFE201612P-R47M=P2 shielded wirewound inductor, 470 nH, 4.8 A, 33 mOhm DCR, 0806, -40°C to 125°C.
