The SMS1770 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors designed for demanding applications. These thin, magnetically shielded inductors feature low DC resistance and exceptional anti-electromagnetic interference capabilities, making them ideal for high-density installations. Their integral construction ensures high reliability and superior vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder for die-casting, these inductors achieve low impedance and small parasitic capacitance, contributing to high efficiency and reduced core eddy-current loss. They operate at frequencies up to 3MHz and have an absolute maximum voltage of 30VDC, complying with RoHS, Halogen Free, and REACH standards.
