Suntsu Introduces Low DCR Power Inductors to Our Product Offering


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.

Suntsu’s SMD power inductors are manufactured with a magnetic shielded structure. This helps them achieve excellent resistance to EMI (Electro-Magnetic Interface), low DCR, and high rated current. 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. This ensures that it can be used in buck converters, laptops, displays, and automotive applications, as well as in network communication equipment.
