High Current Unshielded SMD Power Inductor SPI-HC Series for Low Voltage DC-DC Converters

The SPI-HC series high-current unshielded SMD power inductor is designed for low-voltage high-current DC-DC converters and microprocessor power supply applications. Rated current is up to 51.7A. The product features a low-profile package and ultra-low DCR, effectively reducing power loss and improving system efficiency. The flat top design is suitable for automated pick-and-place assembly. The unshielded open structure offers cost advantage as its core competitiveness. Open-circuit inductance is tested at 100KHz / 250Vrms. Rated current is defined as the RMS current value that causes a temperature rise of approximately 40°C at 85°C ambient temperature. It is widely used in high-current low-voltage DC-DC converters, 3.3V microprocessor power supplies, and CPU power management.
