Suntsu is proud to announce that we have added power inductors to our product offering, as they are an essential component of voltage regulator topology [2].
Suntsu’s SMD power inductors are manufactured with a magnetic shielded structure. This helps them achieve excellent resistance to EMI (Electro-Magnetic Interference), low DCR, and high rated current. In a DC-DC converter, the inductor’s DC resistance is a primary source of conduction loss, so minimizing DCR directly improves power-conversion efficiency [1]. The products were designed with lightweight and small form factors that are ideal for all designs, including high-density board applications.
Suntsu power inductors are available in surface-mount packaging with multiple package sizes. Operating temperature is -40~125°C, and the product is AEC-Q200 compliant [3]. This ensures that it can be used in buck converters, laptops, displays, and automotive applications, as well as in network communication equipment.
