220 µH shielded drum core for DC-DC filtering
The Coilcraft LPS5015-224MRC is a 220 µH shielded drum core inductor in the LPS5015 series, designed for DC-DC converter input and output filtering where low-profile and magnetic shielding are required. Rated for 220 mA DC with a saturation current of 200 mA — the inductance holds within ±20% tolerance up to the saturation knee, making it suitable for power rail smoothing in portable or space-constrained designs. Maximum DC resistance of 4.5 Ohm defines the I²R conduction loss at full rated current, a factor in thermal budget for low-voltage rails.
Self-resonant frequency and operating range
Self-resonant frequency is 7.3 MHz, measured at 100 kHz test frequency — above this point the inductor behaves capacitively, so the usable filtering band stays below ~1-2 MHz for typical buck or boost converters. Shielded ferrite core construction reduces radiated EMI, a practical advantage when the inductor sits near sensitive analog or RF traces on the same board.
Package dimensions and board integration
Supplied in strip packaging, compatible with pick-and-place assembly for medium-volume production runs.
