Molding SMD Power Inductors LanTu Micro SMS1350-100MT with ultra high current and low DC resistance
Molding SMD Power Inductors - SMS1350 Series
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS1350 Series offers ultra-high current SMD power inductors designed for high-density installations. These thin-profile inductors feature low DC resistance and ultra-high current capabilities, coupled with magnetic shielding for strong anti-electromagnetic interference. Their integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder die-casting, these inductors offer low impedance, small parasitic capacitance, high efficiency, and reduced core eddy-current loss, supporting frequencies up to 3MHz and an absolute maximum voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
Applications
Ideal for PDA, notebook, desktop, and server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.
