Molding SMD Power Inductors LanTu Micro SMS1050-5R6MT Featuring Magnetic Shielding and Low Buzz Noise
Molding SMD Power Inductors - SMS1050 Series
Product Overview: The SMS1050 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors designed for demanding applications. These thin, magnetically shielded inductors feature low DC resistance and excellent anti-electromagnetic interference capabilities, making them ideal for high-density installations. Their integral construction ensures high reliability and superior vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder die-casting, these inductors achieve low impedance and small parasitic capacitance, contributing to high efficiency and reduced core eddy-current loss. They are suitable for frequencies up to 3MHz and have an absolute maximum voltage of 30VDC. The SMS1050 series is RoHS, Halogen Free, and REACH compliant.

Note: Saturation Current: DC current at which inductance drops 30% from its value without current. Heat Rating Current: the actual value of DC current when the temperature rise is T 40 (Ta=25). Rated DC Current: The less value which is Isat or Irms. Part temperature should be verified in the end application.
