Molding SMD Power Inductors LanTu Micro SMS0850-100MT with ultra high current and low DC resistance
Molding SMD Power Inductors - SMS0850 Series
Product Overview
The SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. SMS0850 Series offers ultra-high current SMD power inductors designed for high-density installations. These inductors feature a thin profile with low DC resistance and ultra-high current capability, enhanced by magnetic shielding for strong anti-electromagnetic interference. Their integral construction provides high reliability and excellent vibration resistance, while the composite structure minimizes buzz noise. Utilizing low-loss alloy powder for die-casting results in low impedance and small parasitic capacitance, contributing to high efficiency by reducing winding DC resistance and core eddy-current loss. These inductors operate at frequencies up to 1-2MHz and are RoHS, Halogen Free, and REACH compliant.

Notes on Current Ratings:
- 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 lesser of Isat or Irms.
- Special Reminder: Circuit design, component, PCB trace size and thickness, airflow, and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application.
