Molding SMD Power Inductors - SMS1040 Series
Product Overview
The SMS1040 Series by SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors designed for high-density installation. These thin-profile inductors feature low DC resistance, magnetic shielding for strong anti-electromagnetic interference, and an integral construction for high reliability and vibration resistance. Their composite structure minimizes buzz noise, while the low-loss alloy powder die-casting ensures low impedance and small parasitic capacitance, contributing to high efficiency. Suitable for frequencies up to 3MHz and an absolute maximum voltage of 30VDC, these RoHS, Halogen Free, and REACH compliant inductors are ideal for demanding power applications.
