The 1212 footprint with 2.0 mm height provides a compact solution for DC-DC converter energy storage in space-constrained applications. The powdered iron core material offers low core losses at high switching frequencies, while the shielded construction minimizes electromagnetic interference (EMI) with nearby components. With a heat rating current of 3.8 A and saturation current of 4.0 A, it is suitable for moderate-power DC-DC converters in portable and consumer electronics.","working_principle":"The IHLP1212BZER1R5M11 stores energy in its magnetic field when current flows through the wirewound coil around the powdered iron core. In a DC-DC buck converter, the inductor is charged during the switch-on period and discharged during the switch-off period, maintaining continuous current flow to the load. The powdered iron core provides distributed air gaps that prevent core saturation at high DC bias currents, resulting in a soft saturation characteristic. The magnetic shielding confines the magnetic flux within the inductor body, reducing radiated EMI and allowing placement near sensitive components.","pin_description":"
