Overview
The Delevan 103R-561G is an unshielded surface-mount RF inductor with a nominal inductance of 560 nH and a tolerance of ±2%. It features a maximum DC resistance of 278 mΩ and supports a maximum DC current of 590 mA. The component has a self-resonant frequency of 195 MHz and a minimum Q factor of 45 at a test frequency of 25 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.
Feature Summary
- Unshielded construction for minimal magnetic interference
- Surface-mount design for automated assembly
- High self-resonant frequency for RF applications
Applications
- RF circuit filtering
- Impedance matching networks
- General-purpose RF signal processing
Procurement Notes
Verify the specific suffix (e.g., G) against official API Delevan documentation to confirm tolerance and packaging details. Ensure the ordering part number matches the required inductance value and current rating for the target application. Cross-reference manufacturer datasheets for RoHS compliance status and lead time requirements prior to procurement.
Selection Notes
Select this component for applications requiring a 560 nH inductance with low DC resistance. Consider the 590 mA current limit and 195 MHz self-resonant frequency when designing high-frequency circuits. Compare with similar series parts like the 103R-471K or 103R-390KS if different inductance values are needed while maintaining the same footprint.
Part Context
The 103R-561G belongs to the 103/R series of unshielded chip inductors manufactured by API Delevan. This series is designed for general RF applications where size constraints are critical. The component utilizes standard termination options suitable for reflow soldering processes common in modern electronics manufacturing.
Replacement Considerations
Direct substitutes within the same series include the 103R-471K (470 nH) and 103R-390KS (39 nH). Verify that alternative part numbers meet the specific inductance, current, and frequency requirements of the original design before substitution.
