- Leaded axial termination style
Applications
- Radio Frequency circuits
Procurement Notes
Verify the specific manufacturer datasheet for the 105-821K model to confirm exact electrical tolerances, thermal ratings, and mechanical dimensions prior to integration. Ensure that the non-shielded characteristic aligns with the electromagnetic interference requirements of the target RF circuit design.
Selection Notes
Select this component when a leaded, non-shielded RF inductor with 820 nH inductance is required. Consider the 385 mA current rating and 650 mOhm resistance against circuit power constraints. Verify that the axial package fits the board layout compared to surface mount alternatives.
Part Context
This part belongs to the Delevan fixed inductor family, specifically tailored for RF signal processing. It utilizes a wirewound technology suitable for stable performance in high-frequency environments. The leaded format distinguishes it from the manufacturer's broader SMD portfolio.
Replacement Considerations
ER105-821JS is a direct substitute from Delevan.
