Overview
The Delevan 105R-331G is a surface-mount fixed inductor designed for RF applications. It features an unshielded construction with iron core materials, suitable for compact circuit layouts. The component exhibits a nominal inductance of 330 nH and supports a rated current of 620 mA. Its maximum DC resistance is specified at 250 mOhms, ensuring low power loss in signal paths. The unit measures 1.91 mm in height, facilitating integration into space-constrained designs.
Feature Summary
- Unshielded surface-mount design for flexible PCB placement
- Iron core material construction for stable inductance characteristics
- Low profile form factor suitable for high-density assemblies
Applications
- RF signal filtering circuits
- Impedance matching networks
- General-purpose RF inductance applications
Procurement Notes
Verify the manufacturer designation API Delevan or Delevan on the component marking to ensure authenticity. Confirm that the specific suffix 'G' aligns with the required lead-free specifications if applicable to your assembly process. Cross-reference the 250 mOhm resistance value against your schematic requirements to prevent performance deviations in sensitive RF stages.
Selection Notes
Select this component when a small, unshielded inductor with 330 nH inductance is required for RF filtering. Ensure the 620 mA current rating meets the operational load of the target circuit. Consider the 1.91 mm height constraint during mechanical layout planning to avoid clearance issues with adjacent components.
Part Context
This part belongs to the Delevan fixed inductor family, specifically engineered for surface-mount technology. It serves as a passive component for managing radio frequency signals within electronic devices. The unshielded variant allows for easier routing but requires careful placement to minimize electromagnetic interference with nearby traces.
Replacement Considerations
Direct substitutes must match the 330 nH inductance, 620 mA current rating, and 250 mOhm resistance. Verify physical dimensions and mounting type compatibility before substitution.
