Product Description
Molding SMD Power Inductors - SMS1040 Series
Product Overview
The SMS1040 Series from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. offers ultra-high current SMD power inductors with a thin design, low DC resistance, and magnetic shielding for strong anti-electromagnetic interference. These high-reliability inductors feature an integral construction for excellent vibration resistance, ultra-low buzz noise due to composite construction, and die-casting with low-loss alloy powder for low impedance and small parasitic capacitance. They achieve high efficiency and support frequencies up to 3MHz, with an absolute maximum voltage of 30VDC. Compliant with RoHS, Halogen Free, and REACH standards, they are suitable for applications like PDA, notebooks, desktops, servers, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.

Product Identification Example:
SMS 1040 470 M T
- SMS: Type
- 1040: External Dimensions (LWH) (mm)
- 470: Inductance (47 uH)
- M: Inductance Tolerance (20%)
- T: Packing (Tape & Reel)
Definitions:
- 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 between Isat or Irms.
Important Notes:
- 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.
- Storage period is within 12 months. Storage conditions: temperature 5~40C, humidity 35~65% RH or less.
- Do not use or store in locations with gas corrosion (salt, acid, alkali, etc.).
- Avoid touching electrodes directly with bare hands.
- Handle products carefully to prevent damage.
- Do not bend terminals with excessive stress.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering; the temperature difference between solder and chip should not exceed 150C.
- Soldering corrections after mounting should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Self-heating occurs when power is on; ensure sufficient thermal design margin.
- For non-magnetic shield types, carefully lay out the coil on the circuit board to prevent malfunctions due to magnetic interference.
