Overview
The Delevan 105-103H is a fixed RF inductor designed for surface-mount applications. It features an unshielded construction with a ferrite core and two standard leads. The component provides a nominal inductance of 10 µH with a tolerance of ±3%. It supports a maximum DC current of 130 mA and has a maximum DC resistance of 5.6 Ohms. The device operates within a temperature range of -55°C to +125°C.
Feature Summary
- Unshielded SMD design suitable for RF circuits
- Ferrite core construction for stable inductance
- Standard lead termination for PCB mounting
Applications
- RF signal processing circuits
- General purpose filtering applications
- Impedance matching networks
Procurement Notes
Verify the specific manufacturer part number against official Delevan documentation to confirm availability and specifications. Check for any obsolescence notices or lifecycle changes directly from the supplier. Ensure the unshielded variant meets the electromagnetic interference requirements of the target design before finalizing procurement.
Selection Notes
Select this component when an unshielded RF inductor is required for space-constrained surface-mount layouts. Consider the 130 mA current rating and 5.6 Ohm resistance limits relative to circuit load. Verify that the lack of shielding does not cause unwanted coupling in dense PCB arrangements compared to shielded alternatives.
Part Context
This part belongs to the Delevan series of fixed surface-mount inductors. It utilizes a non-standard lead configuration distinct from typical chip inductors. The product line focuses on providing reliable passive components for radio frequency and general electronic applications with consistent performance characteristics.
Replacement Considerations
Consult official Delevan cross-reference lists for direct substitutes. Verify that any replacement maintains the 10 µH value, ±3% tolerance, and 130 mA current rating. Ensure the alternative component matches the physical footprint and lead style if board space is constrained.
