Product Description
Molding SMD Power Inductors - SMS1040 Series
Product Overview
The SMS1040 Series is a line of ultra-high current, thin-profile SMD power inductors designed for high-density installations. Featuring magnetic shielding for strong anti-electromagnetic interference, these inductors offer high reliability with an integral construction for excellent vibration resistance. Their composite structure minimizes buzz noise, while the use of low-loss alloy powder in die-casting results in low impedance, small parasitic capacitance, and high efficiency. Capable of operating at frequencies up to 3MHz with an absolute maximum voltage of 30VDC, these RoHS, Halogen Free, and REACH compliant inductors are suitable for a variety of applications including PDA, notebook, desktop, server applications, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.

Reminders for Using These Products
- 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 direct contact with terminals by bare hands due to oil secretions affecting soldering.
- Handle products carefully to prevent damage from dropping or improper removal.
- Do not bend terminals with excessive stress to avoid wire fracture.
- Do not rinse coils; contact the manufacturer if cleaning is necessary.
- Do not expose products to magnets or magnetic fields.
- Preheat components before soldering; 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.
- Allow sufficient thermal design margin as self-heating occurs when power is on.
- For non-magnetic shield types, careful PCB layout is required to prevent malfunctions due to magnetic interference.
