1.Main Product Types SMD Wire Wound Power Inductors Enameled wire wound on ferrite/iron powder core, low DCR, strong current carrying capability, mainstream for PCB SMT power boards. Shielded Power Inductors Fully magnetic shield structure, low magnetic leakage, reduce EMI interference to adjacent signal circuits. Unshielded Power Inductors Low cost, higher saturation current, suitable for space-unrestricted power modules. Molded Composite Power Inductors Iron powder composite integrated molding, ultra-high saturation current, stable performance under high temperature. Through-Hole Power Inductors Large wire diameter, high inductance and high current, applied to high-power adapters and industrial power supplies. 2.Key Technical Parameters Inductance Range: 0.1μH ~ 1000μH Low DCR (DC Resistance): Reduce power heating loss Saturation Current (Isat): Maximum current before inductance drops sharply Rated RMS Current (Irms): Continuous safe working current Operating Temperature: -40℃ ~ +125℃ Inductance Tolerance: ±10%, ±20% standard for power applications Magnetic shield optional: Shielded / Unshielded 3.Core Advantages High energy storage capacity to stabilize output current of switching power supplies Low DC resistance minimizes heat generation during long-hour operation High saturation current, avoids inductance attenuation under large instantaneous load Shielded versions effectively restrain magnetic radiation interference Complete SMD and through-hole size series, compatible with automated SMT and manual welding Wide temperature adaptability, stable performance for indoor power equipment Cost-effective mass production for general power conversion scenarios 4.Circuit Functions Energy storage & current smoothing for buck / boost DC-DC converters Suppress output current ripple and voltage fluctuation Filter low-frequency and high-frequency interference on power rails Limit inrush current to protect power chips Form LC filter circuits to clean power supply noise 5.Application Fields Laptop & motherboard power circuits, mobile phone chargers & adapters, LED driver power supplies, industrial switching power modules, battery charging management boards, smart home power control units, server auxiliary power, small inverter equipment, consumer electronic power management PCBA.
