560 µH shielded drum core for low-power filtering
The LPS5015-564MRC is a 560 µH shielded drum core inductor in the LPS5015 series from Coilcraft, built for surface-mount DC-DC converter output filters and low-current supply rail smoothing where board height is tight at 1.50 mm seated max. Rated for 140 mA continuous with a saturation floor of 100 mA — the usable current in a buck inductor is the lower of the two, so budget for the saturation limit when the load steps above 100 mA or the core saturates and inductance collapses. 8.5 Ohm maximum DCR at 25°C — at 140 mA the I²R loss is 167 mW, which the 5×5 mm package dissipates without exceeding the 125°C ceiling in still air, but a layout with adjacent heat sources should keep the ambient below 85°C to stay out of derating. Self-resonant frequency is 4.3 MHz — above that the part looks capacitive, so the switching frequency of the converter should stay below 1 MHz to keep the inductor in its inductive region with margin.
Shielded construction and temperature range
Shielded ferrite core contains the magnetic field — the leakage flux is low enough that this inductor can sit next to a sensitive analog trace or a WLAN module without coupling noise into the signal path. Inductance tested at 100 kHz — the 560 µH value holds at that frequency; above 1 MHz the effective inductance drops as the core permeability rolls off, so the 4.3 MHz SRF is the practical ceiling.
The part ships in strip packaging, compatible with pick-and-place assembly; the nonstandard 5×5 mm footprint is shared across the LPS5015 series, so a reel change is the only BOM adjustment if the value changes.
