Overview
The Delevan 105-821G is a fixed RF inductor designed for surface-mount applications. It features an 820 nH nominal inductance with a ±20% tolerance. The component supports a maximum DC current of 385 mA and exhibits a maximum DC resistance of 650 mOhms. It operates within a temperature range of -55°C to +105°C. The unit utilizes an unshielded construction with a nonstandard two-lead package, measuring 2.54 mm in length and width, and 1.65 mm in height.
Feature Summary
- Surface-mount configuration with nonstandard two-lead termination
- Unshielded design suitable for general RF circuit integration
- Operational stability across extended industrial temperature ranges
Applications
- RF signal processing circuits
- General-purpose electronic filtering
- Industrial equipment signal conditioning
Procurement Notes
Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with surface-mount assembly processes and validate that the unshielded topology meets the electromagnetic interference requirements of the target application environment.
Selection Notes
Select this component based on its 820 nH inductance value and 385 mA current rating. Consider the unshielded nature when designing layouts to prevent magnetic coupling with adjacent components. Confirm that the 650 mOhm DC resistance aligns with power loss constraints in the specific circuit path.
Part Context
This component belongs to the Delevan fixed inductor family, specifically engineered for radio frequency applications. It represents a standard passive component used for impedance matching and filtering in electronic systems requiring reliable performance under varying thermal conditions.
Replacement Considerations
Cross-reference with other Delevan series such as the 100 or 105 series for similar inductance values. Verify pinout compatibility and current handling capabilities before substituting with alternative manufacturers' offerings.
