Product Features
● 2.2µH Inductance, ±20% Typical: Marked 2R2 on the top face for easy identification.● High Current Capability: Flat-wire winding on an alloy core for high-current power rails.● Flat Copper Wire Winding: Rectangular ribbon conductor instead of round wire.● Low DC Resistance: The flat conductor keeps DC resistance down compared with round-wire windings.● Low AC Losses: Reduced skin effect at high frequency keeps switching losses low.● Iron-Based Alloy Core: High saturation, suitable for power applications.● Magnetically Shielded Construction: The enclosed magnetic path reduces EMI and crosstalk on dense boards.● Tinned Copper Terminals: Good solderability for reflow assembly.● SMD Mounting: Fully surface-mount construction, no through-holes or hand wiring.● Wide Operating Temperature: -40°C to +125°C.
Product Advantages
● 2.2µH (±20% typical) winding: a low inductance value for high-current DC-DC converter stages, in a surface-mount body.● Flat copper wire instead of round wire: the rectangular conductor lowers DC resistance and reduces skin effect at high frequency.● Iron-based alloy core: high saturation flux density lets the inductor carry large currents before the core saturates.● Magnetically shielded construction: the closed magnetic path contains the flux, reducing EMI and crosstalk in dense PCB layouts.● Low DC resistance: lower I²R loss means higher converter efficiency and less heat to manage.● Surface-mount termination: tinned copper terminals reflow directly onto the board pads, which removes through-holes and hand wiring from the assembly.● Wide operating temperature range, -40°C to +125°C: stable performance in high-temperature power circuits.
