Procurement Notes
Verify the specific suffix 'KS' against official manufacturer documentation to confirm packaging and compliance details. Ensure the ordering quantity aligns with the factory reel requirements specified in the datasheet. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current production status before finalizing procurement.
Selection Notes
Select this component when a 1.2 µH inductance value is required for RF circuits operating near 130 MHz self-resonance. Consider the 360 mA current rating and 0.74 Ω DC resistance for power handling constraints. The unshielded design requires careful layout consideration to minimize electromagnetic interference with adjacent components on the printed circuit board.
Part Context
This part belongs to the Delevan 103/R series of fixed RF inductors. These components are designed for surface-mount technology and utilize a rectangular form factor. The series offers various inductance values tailored for radio frequency applications, providing a standardized footprint for integration into electronic assemblies requiring passive RF filtering or tuning elements.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative manufacturers by matching inductance, current rating, and physical dimensions.
