Fixed Inductors Procurement Notes

Verify the specific suffix 'YL' against the manufacturer's official datasheet to confirm lead-free compliance and tape-and-reel packaging specifications. Ensure the ordered part matches the exact inductance value and current ratings required by the circuit design. Cross-reference the manufacturing date code to guarantee material integrity and avoid counterfeit components during the sourcing process.

Fixed Inductors Selection Notes

Select this component when a shielded inductor is required to reduce magnetic coupling in dense PCB layouts. The 8.2µH value suits moderate frequency switching applications. Evaluate the 1.1A saturation current limit against peak load requirements. The low profile fits within strict height constraints while maintaining thermal stability for continuous operation in regulated power environments.

Fixed Inductors Part Context

This part belongs to the SRR4011 series of shielded power inductors manufactured by Bourns Inc. The series utilizes a robust wirewound construction on a drum core, offering consistent electrical characteristics across various operating temperatures. It is engineered for reliability in industrial and consumer electronics where space efficiency and electromagnetic compatibility are critical design parameters.

Fixed Inductors Replacement Considerations

Consult the official Bourns SRR4011 series documentation for direct cross-references. Verify that alternative parts match the 4.8x4.8mm footprint, 8.2µH inductance, and 1.1A current rating. Ensure equivalent shielding and DC resistance values to maintain circuit performance without redesigning the PCB layout.
