Product Description
Molding SMD Power Inductors - SMS0530 Series
Product Overview
The SMS0530 Series is a line of ultra-high current, thin-design SMD power inductors featuring magnetic shielding for strong anti-electromagnetic interference. Constructed with an integral molding for high reliability and vibration resistance, these inductors offer low DC resistance, ultra-low buzz noise due to composite construction, and low eddy-current loss from die-casting with low-loss alloy powder. They are suitable for high-density installations and operate efficiently up to 3MHz. Applications include PDA, notebook, desktop, and server systems, high current POL converters, battery-powered devices, and DC/DC converters in distributed power systems.

Reminders for Using These Products
- Storage: Within 12 months, under conditions (5~40C, 35~65% RH). Terminal solderability may degrade if storage period is exceeded.
- Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
- Handling: Avoid direct contact with terminals by bare hands due to oil secretions that can inhibit soldering. Handle products carefully to prevent damage from dropping or improper removal.
- Terminal Bending: Do not bend terminals with excessive stress to avoid wire fracture.
- Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
- Magnetic Fields: Do not expose products to magnets or magnetic fields.
- Preheating: Preheat components before soldering. The temperature difference between solder and chip should not exceed 150C.
- Soldering Corrections: Post-mounting soldering corrections should be within specified conditions. Overheating may cause short circuits, performance degradation, or reduced lifespan.
- Thermal Design: Allow sufficient margin for thermal design due to self-heating when power is on.
- Non-Magnetic Shield Type: Careful layout is required on the PCB to prevent malfunctions due to magnetic interference.
