Molding SMD Power Inductors - SMS1040 Series

Product Overview

The SMS1040 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. features ultra-high current SMD power inductors with a thin design, low DC resistance, and excellent anti-electromagnetic interference capabilities due to magnetic shielding. These inductors are ideal for high-density installations and offer high reliability with superior vibration resistance owing to their integral construction. The composite structure minimizes buzz noise, while the low-loss alloy powder die-casting ensures low impedance and small parasitic capacitance, leading to high efficiency. Suitable for frequencies up to 3MHz and an absolute maximum voltage of 30VDC, these inductors comply with RoHS, Halogen Free, and REACH standards.

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 lesser value of Isat or Irms.
  • Part temperature should be verified in the end application due to factors like circuit design, component, PCB trace size and thickness, airflow, and other cooling provisions.

Reliability Testing

Refer to the provided document for detailed reliability testing items, requirements, and test methods including Terminal Strength, Resistance to Flexure, Dropping, Solderability, Vibration, Thermal Shock, Low temperature Storage, High temperature Storage, Damp Heat, Heat endurance of Reflow soldering, Resistance to solvent test, Overload test, and Voltage resistance test.

Recommended Reflow Soldering Curve

The recommended reflow conditions are set according to the manufacturer's soldering equipment. Users should adjust and confirm conditions based on their specific environment and equipment. Preheating is required before soldering, with a temperature difference between the solder and chip temperature not exceeding 150C.

Reminders for Using These Products

  • Storage: Within 12 months, under conditions of 5~40C and 35~65% RH.
  • Environment: Avoid use and storage in gas corrosive environments (salt, acid, alkali, etc.).
  • Handling: Avoid direct contact with terminals with bare hands. Handle products carefully to prevent damage.
  • Terminals: Do not bend terminals excessively.
  • Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
  • Magnetic Fields: Do not expose to magnets or magnetic fields.
  • Soldering: Preheat components before soldering. Soldering corrections after mounting should be within specified conditions. Overheating may cause issues.
  • Self-heating: Allow sufficient thermal design margin for self-heating when power is on.
  • Layout: For non-magnetic shielded types, careful coil placement on the PCB is advised to prevent malfunctions due to magnetic interference.
