Molded SMD power inductors LanTu Micro SMS0420 4R7MT with low DC resistance and strong EMI shielding
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0420 Series are ultra-high current, molded SMD power inductors designed for high-density installations. 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. The integral construction ensures high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. They are manufactured using low-loss alloy powder for die-casting, resulting in low impedance and small parasitic capacitance, contributing to high efficiency and reduced core eddy-current loss. These inductors support frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. They are RoHS, Halogen Free, and REACH compliant.
Applications include: PDA, notebook, desktop, server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.

Reliability Testing: Includes Terminal Strength, Resistance to Flexure, Dropping, Solderability, Vibration, Thermal Shock, Low Temperature Storage, High Temperature Storage, Damp Heat (Steady States), Heat endurance of Reflow soldering, Resistance to solvent test, Overload test, and Voltage resistance test.
Recommended reflow soldering curve: Conditions to be adjusted and confirmed according to user's environment/equipment.
Reminders for Using These Products: Storage period within 12 months under specified conditions (5~40C, 35~65% RH). Avoid use and storage in corrosive gas environments. Do not touch terminals directly with bare hands. Handle with care to prevent damage. Avoid excessive bending of terminals. Do not rinse coils without consulting the company. Keep away from magnets or magnetic fields. Preheat components before soldering. Soldering corrections after mounting should be within specified conditions. Allow for self-heating in thermal design. For non-magnetic shielded types, careful layout is needed to avoid malfunction due to magnetic interference.
