Overview
The Delevan 103R-102H is an unshielded surface-mount RF inductor with a nominal inductance of 1 µH and a tolerance of ±3%. It features a maximum DC resistance of 540 mΩ and supports a maximum DC current of 425 mA. The component utilizes a nonstandard two-lead SMD package with dimensions of 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. Designed for radio frequency applications, it operates within a temperature range of -55°C to +125°C.
Feature Summary
- Unshielded chip construction suitable for RF signal processing
- Ferrite core technology for stable inductance performance
- Surface-mount design optimized for PCB integration
Applications
- Radio frequency circuit filtering
- Impedance matching networks
- RF signal conditioning
Procurement Notes
Verify the manufacturer designation carefully, as API Delevan assets have been acquired by other entities. Confirm RoHS compliance status through the latest official datasheet or product change notification. Ensure the specific suffix matches the required tolerance and packaging format for your production line requirements.
Selection Notes
Select this component when an unshielded form factor is required to minimize parasitic capacitance in high-frequency designs. The 1 µH value and 425 mA current rating suit moderate power RF stages. Verify that the physical footprint fits 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 RF inductors manufactured by Delevan. These components are characterized by their compact nonstandard footprint and unshielded architecture. The series is engineered for general-purpose radio frequency applications where size constraints and signal integrity are primary design considerations.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires manual verification of electrical parameters and physical dimensions against alternative manufacturers' catalogs.
