Product Features
● 2.2µH inductance, typical ±20%: Marked 2R2 on top for easy identification. ● High current capability: Flat wire wound on alloy core, suitable for high current power circuits. ● Flat copper wire winding: Uses rectangular ribbon conductors instead of round wire. ● Low DC resistance: Flat conductors reduce DC resistance compared to round wire windings. ● Low AC losses: Reduced skin effect at high frequencies, lowering switching losses. ● Iron-based alloy core: High saturation characteristics, suitable for power applications. ● Magnetic shielded structure: Closed magnetic circuit reduces EMI and crosstalk on high-density boards. ● Tin-plated copper terminals: Good solderability, suitable for reflow soldering. ● SMD mounting: Fully surface mount structure, no through-hole or manual wiring. ● Wide operating temperature range: -40°C to +125°C.
Product Advantages
● 2.2µH (typical ±20%) winding: Low inductance suitable for high current DC-DC conversion stages in SMD package. ● Flat copper wire replaces round wire: Rectangular conductors reduce DC resistance and minimize high-frequency skin effect. ● Iron-based alloy core: High saturation flux density allows the inductor to carry higher current before core saturation. ● Magnetic shielded structure: Closed magnetic circuit confines flux, reducing EMI and crosstalk in high-density PCB layouts. ● Low DC resistance: Lower I²R losses mean higher converter efficiency and less thermal management required. ● Surface mount terminals: Tin-plated copper terminals reflow soldered directly to PCB pads, eliminating through-hole and manual wiring during assembly. ● Wide operating temperature range -40°C to +125°C: Maintains stable performance in high-temperature power circuits.
