Procurement Notes
Verify the specific suffix 'K' against official API Delevan documentation to confirm tolerance and termination specifications. Ensure the procurement channel provides valid manufacturer traceability. Cross-reference the datasheet revision date to ensure compliance with current RoHS and lead-free status requirements before finalizing orders.
Selection Notes
Select this component for applications requiring a 0.27 µH inductance with a 10% tolerance in a standard 1010 footprint. Consider the 0.23 Ω DC resistance for power loss calculations. Verify that the operating temperature range of -55°C to 125°C meets the environmental demands of the target assembly.
Part Context
This part belongs to the API Delevan fixed inductor family, specifically designed for surface-mount technology. It shares the 105 series form factor with other variants like the 105-272F, differing primarily in inductance value and tolerance specifications while maintaining similar physical dimensions and mounting characteristics.
Replacement Considerations
Direct substitutes include the 105-271K variant, which offers identical electrical parameters but may differ in tolerance or packaging details. Verify compatibility with the 105R-271HS if higher current handling is required, ensuring pinout and thermal performance align with the original design.
