Overview
The Delevan 103R-331G is an unshielded surface-mount RF inductor with a non-standard package design featuring two leads. It provides an inductance of 330 nH (0.33 uH) with a tolerance of 2%. The component has a maximum DC resistance of 235 mOhms and supports a maximum DC current of 645 mA. It is designed for PCB mounting applications requiring precise RF signal handling.
Feature Summary
- Unshielded construction for minimal magnetic interference
- Non-standard two-lead surface-mount configuration
- Ferrite core technology for stable RF performance
Applications
- RF circuit filtering
- Impedance matching networks
- High-frequency signal processing
Procurement Notes
Verify the specific package dimensions against the official datasheet due to the non-standard lead configuration. Confirm that the 645 mA current rating aligns with your circuit's thermal requirements. Ensure the unshielded nature does not cause coupling issues in dense layouts. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a compact, unshielded RF inductor with low DC resistance is required. The non-standard footprint necessitates custom PCB land patterns. Consider the 2% tolerance for precision applications. Evaluate space constraints carefully as the two-lead design differs from standard SMD footprints. Verify compatibility with automated assembly processes if applicable.
Part Context
This part belongs to Delevan's fixed inductor lineup, specifically targeting RF and high-frequency applications. It complements other unshielded series by offering a distinct two-lead form factor. The product line emphasizes reliability in sensitive electronic environments where shielding might introduce unwanted parasitic effects or size constraints.
Replacement Considerations
Direct substitutes include parts with identical 330 nH inductance, 2% tolerance, and similar current ratings. Check for compatible non-standard footprints or adjust PCB layout for alternative packages. Verify that replacement components maintain the same unshielded characteristic and DC resistance limits to ensure circuit integrity.
