Overview
The Delevan 103R-272FS is a fixed surface-mount RF inductor with an inductance of 2.7 µH and a tolerance of 1%. It features a nonstandard two-lead package design, distinguishing it from standard SMD footprints. The component has a maximum DC resistance of 1.15 Ohms and supports a maximum current of 290 mA. It is designed for general-purpose RF applications requiring precise inductance values.
Feature Summary
- Nonstandard two-lead surface mount configuration
- High precision 1% inductance tolerance
- Shielded construction to minimize electromagnetic interference
Applications
- RF signal filtering circuits
- Impedance matching networks
- General-purpose RF choke applications
Procurement Notes
Verify the specific lead configuration against PCB footprint requirements due to the nonstandard package type. Confirm that the 290 mA current rating meets circuit demands. Ensure compatibility with assembly processes for two-lead SMD components. Cross-reference the 1.15 Ohm DC resistance with thermal management needs.
Selection Notes
Select this component when a precise 2.7 µH value is required with tight 1% tolerance. The nonstandard two-lead package offers mechanical advantages over standard SMD forms in specific layouts. Consider the 290 mA current limit for power handling. Evaluate the 1.15 Ohm resistance for voltage drop considerations in low-voltage RF paths.
Part Context
This part belongs to the Delevan 103/R series of RF inductors. It shares the core electrical characteristics of the series but utilizes a distinct nonstandard two-lead package instead of the typical SMD form factor. This variation provides alternative mounting options while maintaining the high Q-factor and stability expected from the manufacturer's RF line.
Replacement Considerations
Direct substitutes include the 103-272FS, which shares identical electrical specifications but may differ in package details. Verify physical dimensions and lead spacing before substitution. Other 2.7 µH RF inductors with similar tolerance and current ratings may be considered if package constraints allow.
