Procurement Notes
Verify the exact suffix against official manufacturer documentation to confirm electrical tolerances and specifications. Datasheet availability should be confirmed directly with API Delevan or authorized distributors. Ensure the ordering code matches the required 2% tolerance and 430 mA current rating before finalizing procurement orders.
Selection Notes
Select this component when an unshielded SMD inductor with 820 nH inductance is required. Consider the 160 MHz self-resonant frequency for high-frequency operation limits. Evaluate the 430 mA current handling capability against circuit load requirements. Compare physical footprint constraints with available PCB space.
Part Context
This part belongs to the Delevan 103/R series of fixed RF inductors. These components are designed for surface-mount technology and are commonly used in radio frequency circuits. The series offers various inductance values and tolerances to support diverse RF design needs.
Replacement Considerations
Cross-reference with other 103-series variants such as 103-821HS or 103R-821HS if different tolerance levels (e.g., 3%) or packaging options are acceptable. Verify that substitute parts maintain compatible physical dimensions and electrical characteristics.
