| Package | SMD,3x3mm | Model Number | STC303020-4R7MT |
The LANTU STC303020 series T-core molding structure power inductors are designed for high-density installation with excellent anti-electromagnetic interference capabilities. These thin-profile inductors offer low DC resistance and ultra-high current handling, making them ideal for high switching frequencies. Their T-core molding structure ensures high reliability and superior vibration resistance. They are compliant with RoHS, Halogen Free, and REACH standards.
