LQM18PN4R7MFRL

LQM18PN4R7MFRL is a 4.7 µH ±20% multilayer power inductor from Murata in a 0603 (1608 metric) case — ferrite-shielded, from the low-DCR LQM18PN line, and Murata's product record lists this part as In Production. The figures from Murata's record: rated current 620 mA maximum on the temperature-rise basis (this type publishes no saturation-current row — do not borrow one from a sibling), DC resistance 0.55 Ω maximum (0.44 Ω ±25% nominal), self-resonant frequency 40 MHz minimum, dimensions 1.6 x 0.8 x 0.8 mm (±0.15 mm). Read the temperature range on this type carefully: the operating ceiling is +85 °C, not the +125 °C of the FN line. The final L is the 180 mm embossed-tape reel at 4,000 pieces. The selection point is shielded 4.7 µH in 0603 for converter rails in compact devices. Selection advice: with no Isat row published, the inductance under load must be checked against Murata's L-versus-current data for this code before the design is frozen.
