Procurement Notes
Verify the specific suffix 'KS' against official API Delevan documentation to confirm packaging and tolerance specifications. Ensure compatibility with standard SMT assembly processes given the component's physical dimensions. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.
Selection Notes
Select this component when an unshielded inductor is required for RF applications operating near 215 MHz. Consider the 610 mA current rating and 260 mΩ DC resistance for power handling requirements. The 103/R series form factor suits designs needing compact footprint without magnetic shielding constraints.
Part Context
This component belongs to the Delevan 103/R series of fixed RF inductors. These parts are designed for high-frequency applications requiring stable inductance values. The series offers various inductance options within a consistent surface-mount package style, facilitating standardized design practices across different RF circuit configurations.
Replacement Considerations
Consult official substitution guides for equivalent unshielded RF inductors with matching 470 nH inductance and similar current ratings. Verify that alternative components meet the same self-resonant frequency and Q factor requirements for the specific application.
