Product Description
High Efficiency Shielded 2R2 Molded Inductor for Stable DC-DC Power Supply
Elite Performance Energy Storage: 2.2µH (2R2) High-Current Molded Power Inductor
Product Introduction & Strategic Selling Points
The "2R2" Series SMD Power Inductor, representing a precisely calibrated 2.2 microhenry inductance value, is a high-performance energy storage component specifically engineered for the high-density requirements of modern DC-DC conversion and Voltage Regulator Modules (VRMs).
High-Flux Metallic Alloy Core
Proprietary blend of iron-based alloy powders providing significantly higher saturation current (Isat) than traditional magnetic materials.
Integrated Magnetic Shielding
Natural Faradic shield around the internal coil drastically reduces radiated electromagnetic interference (EMI).
Ultra-Low DC Resistance (DCR)
Exceptionally low resistive losses achieved through maximized "Window Fill Factor" and high-cross-section conductive paths.
Soft Saturation Characteristic
Gradual saturation curve provides vital safety margin during unexpected over-current events.

Product Features & Advanced Manufacturing Advantages
Integrated Molded Structure
Single, homogeneous magnetic block eliminating internal air gaps that cause magnetic flux leakage and mechanical instability.
Metallic Alloy Powder Technology
Proprietary blend of high-purity iron, silicon, and aluminum powders with nanometer-scale insulation coating.
Vacuum Pressure and Sintering Control
Precisely controlled curing cycle stabilizes chemical bonds, making units moisture-proof and resistant to corrosive gases.
EMI/EMC Self-Shielding Benefit
Metallic alloy core acts as natural shield, containing magnetic flux within component housing.
