The STC201610 series T-core molding structure power inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are designed for high-density installation applications. They feature a thin profile with low DC resistance and ultra-high current capabilities, making them ideal for high switching frequencies. The magnetic shielding provides strong anti-electromagnetic interference. These inductors offer high reliability and excellent vibration resistance due to their T-core molding structure. They are compliant with RoHS, Halogen Free, and REACH standards.
