The high saturation design handles 21 A peak current without inductance collapse, making it ideal for applications with high transient current spikes. The 11.5 A heat rating current ensures thermal stability during continuous operation. The metal composite core construction provides ultra-low buzz noise and eliminates the acoustic noise issues common with ferrite core inductors. The shielded construction minimizes EMI radiation to surrounding components. The low 2.0 mm profile enables use in height-constrained designs.","working_principle":"The IHLP2020BZERR47M01 stores energy in its magnetic field when current flows through the windings. In a DC-DC converter, the inductor alternately stores and releases energy during each switching cycle, smoothing the pulsed current into a continuous output. The 470 nH inductance value is suitable for high-frequency converters (500 kHz to several MHz) where low inductance values are preferred. The metal composite core provides a soft saturation characteristic where inductance decreases gradually with increasing current, rather than the abrupt saturation of ferrite cores. This soft saturation behavior allows the inductor to handle current spikes without catastrophic loss of inductance.","pin_description":"
