Overview
The Delevan 103R-101MS is an unshielded surface-mount RF inductor with a nominal inductance of 100 nH and a tolerance of ±20%. It features a maximum DC resistance of 230 mΩ and supports a maximum DC current of 650 mA. The component measures 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. Designed for RF applications, it utilizes standard terminals and operates within a temperature range defined by the series specifications.
Feature Summary
- Unshielded construction suitable for general-purpose RF circuits
- Surface-mount design for automated PCB assembly
- Standard terminal configuration for reliable connectivity
Applications
- RF signal processing circuits
- General-purpose inductive filtering
- High-frequency impedance matching networks
Procurement Notes
Verify the specific manufacturer datasheet to confirm RoHS compliance status and exact operating temperature limits. Ensure the selected packaging format aligns with automated placement requirements. Cross-reference the maximum DC current rating against circuit load conditions to prevent saturation or thermal issues during operation.
Selection Notes
Select this component when a compact, unshielded inductor is required for RF frequencies near 100 nH. Consider the 230 mΩ DC resistance impact on circuit efficiency. Verify that the physical dimensions fit the available board space and that the unshielded nature does not cause interference with nearby sensitive traces.
Part Context
This part belongs to the 103R series of fixed inductors manufactured by API Delevan. The series offers various inductance values in a consistent 1010 (2525 metric) package size. These components are designed for high-frequency applications where low profile and standard mounting are prioritized over magnetic shielding.
Replacement Considerations
Direct substitutes include other 100 nH ±20% SMD inductors in the 2525 package from compatible manufacturers. Verify equivalent DC resistance and current ratings. Check if shielded alternatives are acceptable if EMI mitigation becomes necessary.
