Fixed Inductors Procurement Notes
Verify the manufacturer part number ATNR5040M4R7MT against official Arlitech Electronic Corp documentation to confirm specifications. Ensure compatibility with SMD/SMT placement requirements and check for moisture sensitivity labeling if storage conditions are critical. Cross-reference the 2020 package dimensions with PCB layout constraints.
Fixed Inductors Selection Notes
Select this component when a compact 4.7 µH inductor with 3.2 A current handling is required. The 30 mΩ resistance value influences efficiency calculations in low-voltage applications. The shielded design is suitable for noise-sensitive environments such as display panels. Confirm that the 5050 metric footprint aligns with existing board space limitations.
Fixed Inductors Part Context
Arlitech Electronic Corp specializes in inductor components primarily serving the LCD panel industry. The ATNR5040 series represents their surface mount power inductor line, characterized by shielded wirewound technology. This specific model is part of a broader family offering various inductance values within the same physical package constraint.
Fixed Inductors Replacement Considerations
Consult official distributor databases for direct cross-references. Generic equivalents must match the 4.7 µH inductance, 3.2 A current rating, 30 mΩ resistance, and 2020 package size.
