103R-221H

Overview

The Delevan 103R-221H is a fixed surface-mount RF inductor with a nominal inductance of 220 nH and a tolerance of 3%. It features an unshielded construction with a maximum DC resistance of 220 mOhms and a rated DC current of 665 mA. The component operates within a temperature range of -55°C to +125°C, exhibits a minimum Q factor of 25, and has a self-resonant frequency of 45 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.

Feature Summary

Unshielded SMD design for minimal magnetic interference
High thermal stability across extended operating temperatures
Low DC resistance for efficient power handling

Applications

RF circuit filtering
Impedance matching networks
General purpose RF applications

Procurement Notes

Verify the specific manufacturer datasheet for the 103R-221H to confirm RoHS compliance status and detailed electrical tolerances. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as availability may vary by distributor. Cross-reference the part number against official API Delevan documentation to validate current production status and lead times before finalizing procurement plans.

Selection Notes

Select this component when an unshielded RF inductor with 220 nH inductance is required for PCB-mounted applications. Consider the 665 mA current rating and 220 mOhm resistance for power efficiency needs. Verify that the 45 MHz self-resonant frequency aligns with the target signal bandwidth. Ensure the 1010 package footprint fits the available board space constraints.

Part Context

The 103R-221H belongs to the Delevan 103/R series of fixed inductors designed for radio frequency environments. This series utilizes phenolic core materials and rectangular constructions to provide stable inductance values. The product falls under the broader category of passive components, specifically serving as a general-purpose inductor for electronic circuits requiring precise RF characteristics.
