Overview
The Delevan 103R-222K is a fixed surface-mount RF inductor with a nominal inductance of 2.2 µH and a tolerance of ±10%. It features a maximum DC resistance of 1 Ohm and a rated current of 310 mA. The component utilizes a phenolic core material and is housed in a 1010 (2525 metric) rectangular package measuring 2.54 mm in length, 2.03 mm in width, and 1.91 mm in height. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Utilizes a phenolic core material for stable inductance characteristics
- Designed for surface-mount PCB assembly applications
- Provides unshielded construction suitable for general-purpose RF circuits
Applications
- RF signal processing circuits
- General-purpose inductive filtering
- High-frequency impedance matching networks
Procurement Notes
Verify the specific manufacturer designation, as API Delevan assets were acquired by TDK Corporation. Confirm that the supplier provides components manufactured under the original API Delevan specifications or valid TDK equivalents. Ensure the part number matches the exact 1010 package dimensions and phenolic core composition required for the design.
Selection Notes
Select this component when a compact 2.2 µH inductor is required for RF applications with moderate current handling needs. The 1 Ohm DC resistance and 310 mA rating define its power limitations. Consider the unshielded nature of the device regarding potential electromagnetic interference coupling in dense layouts.
Part Context
This component belongs to the 103R series of fixed SMD inductors from Delevan. The series offers various inductance values in a standardized 1010 footprint, providing a consistent mechanical profile for board space-constrained designs while maintaining reliable electrical performance across wide temperature ranges.
Replacement Considerations
Consult TDK Corporation documentation for direct replacements following the acquisition of API Delevan's passive component business. Verify equivalent inductance, tolerance, and physical dimensions before substitution.
