Fixed Inductors Procurement Notes

Verify the manufacturer part number SRR1280-681K against official Bourns documentation to confirm specifications. Ensure compatibility with peak current requirements and thermal management constraints. Check for RoHS compliance status and automotive qualification if applicable to the target application environment.

Fixed Inductors Selection Notes

Select this component when a shielded inductor with 680 µH nominal value is required. Consider the 750 mA saturation current limit and 1.3 Ohm DC resistance for efficiency calculations. Evaluate the 12.5 mm x 12.5 mm footprint against available PCB space and ensure operating temperatures remain within the specified -40°C to +125°C range.

Fixed Inductors Part Context

This component belongs to the Bourns SRR1280 series of shielded SMD power inductors. The series utilizes wirewound construction on ferrite cores to provide robust magnetic shielding. These inductors are designed for general power applications requiring reliable inductance values in surface-mount formats.

Fixed Inductors Replacement Considerations
