2.2 mH shielded inductor in a 5 mm footprint
The Coilcraft LPS5015-225MRC is a shielded drum core inductor rated for 2.2 mH inductance with a ±20% tolerance, tested at 100 kHz. Its 65 mA continuous current rating and 72 mA saturation current define the load ceiling for DC-DC converter output filters or power-line smoothing in space-constrained designs.
Self-resonant frequency and application fit
With a self-resonant frequency of 2.1 MHz, this inductor remains inductive well above typical switching frequencies for small DC-DC converters (500 kHz to 1 MHz). Above SRF the impedance turns capacitive, so the converter's switching fundamental and its harmonics should stay below 2.1 MHz to avoid unexpected filtering behavior. The shielded construction contains the magnetic field within the ferrite core, reducing radiated EMI coupling to nearby traces or components — useful when the inductor sits adjacent to sensitive analog circuitry or RF front-ends on the same board.
Lifecycle and supply posture
Coilcraft lists the LPS5015-225MRC as Active, meaning the manufacturer continues production with no announced end-of-life.
