Fixed Inductors Procurement Notes
Verify the specific suffix against the manufacturer datasheet to confirm exact electrical tolerances and packaging configurations. Ensure the ordering part number matches the required inductance value and current ratings for the target circuit design. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.
Fixed Inductors Selection Notes
Select this component when a compact shielded inductor is required for moderate current applications. The 12.5 mm square footprint allows for dense PCB layouts. Consider the saturation current limit relative to peak load conditions to prevent performance degradation during transient states.
Fixed Inductors Part Context
This part belongs to the DR series of high-power shielded drum core inductors from Eaton Electronics. The series offers various inductance values optimized for different power levels while maintaining a consistent mechanical profile for standardized board designs.
Fixed Inductors Replacement Considerations
Cross-reference with other shielded SMD inductors sharing identical 12.5x12.5x8mm dimensions and 1mH inductance. Verify that substitute parts meet or exceed the 1.14A saturation current and 1.66 Ohm DCR specifications.
