Overview
The Delevan 103R-221K is a fixed surface-mount RF inductor with a nominal inductance of 220 nH and a tolerance of ±10%. It features an unshielded construction using iron core material, designed for general-purpose RF applications. The component supports a maximum DC current of 665 mA and exhibits a maximum DC resistance of 220 mΩ. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and a maximum height of 1.91 mm. The device operates within a temperature range of -55°C to 125°C and meets MIL-PRF-83446/04 military specifications.
Feature Summary
- Unshielded chip inductor design suitable for RF circuits
- Compliance with MIL-PRF-83446/04 military specifications
- Iron core construction for stable inductance characteristics
Applications
- RF circuit filtering
- General-purpose RF inductance requirements
- Military electronic assemblies
Procurement Notes
Verify the specific suffix designation against official API Delevan documentation to confirm exact electrical tolerances and terminal configurations. Ensure compatibility with MIL-PRF-83446/04 standards if required for defense or aerospace projects. Confirm package orientation and pinout details prior to PCB layout finalization.
Selection Notes
Select this component for applications requiring a compact 1008 metric footprint with unshielded performance. Consider the 665 mA current rating and 220 mΩ resistance when designing power-sensitive RF stages. Evaluate thermal management capabilities given the 125°C maximum operating temperature limit.
Part Context
This part belongs to the Micro i series of chip inductors manufactured by API Delevan. The series provides various inductance values optimized for radio frequency signal processing. The 103R-221K specifically addresses needs for low-profile mounting in dense surface-mount layouts.
Replacement Considerations
Cross-reference with other 1008 footprint unshielded inductors from API Delevan or alternative manufacturers offering identical 220 nH values. Verify that substitute components meet the same MIL-PRF-83446/04 reliability standards and dimensional constraints.
