Compact and Molding SMD Power Inductors LanTu Micro SMS0420-1R0MT with ultra high current capacity
Molding SMD Power Inductors - SMS0420 Series
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0420 Series Ultra-high current SMD power inductors are designed for high-density installation with a thin profile, low DC resistance, and ultra-high current capabilities. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors offer high reliability through an integral construction that provides excellent vibration resistance. Their composite structure minimizes buzz noise, while the use of low-loss alloy powder in a die-casting process results in low impedance, small parasitic capacitance, and high efficiency. These inductors are suitable for applications requiring frequencies up to 3MHz and an absolute maximum voltage of 30VDC, and comply with RoHS, Halogen Free, and REACH standards.
