Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0420 Series are ultra-high current SMD power inductors designed for high-density installation. Featuring a thin profile with low DC resistance and ultra-high current capabilities, these inductors offer strong anti-electromagnetic interference due to their magnetic shielding. Their integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder for die-casting, they provide low impedance and small parasitic capacitance, contributing to high efficiency and reduced core eddy-current loss. These inductors are suitable for frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
