0819-24F

Overview

The Delevan 0819-24F is a leaded RF inductor featuring an axial termination style and unshielded molded construction. It provides an inductance of 1 µH with a tight tolerance of 1%. The component supports a maximum DC current of 435 mA while maintaining a maximum DC resistance of 250 mOhms. Key electrical characteristics include a minimum Q factor of 40 and a self-resonant frequency of 250 MHz. Designed for PCB mount applications, it measures 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Unshielded molded coil design for RF signal processing
• Axial leaded termination for standard PCB mounting
• High precision 1% inductance tolerance

Applications

• RF circuit filtering
• Impedance matching networks
• Signal conditioning in radio frequency systems

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status directly with the supplier, as documentation varies. Ensure the ordering quantity aligns with factory pack requirements, typically sold in reels of 1000 units. Cross-reference the datasheet to confirm the exact electrical parameters match the application requirements before finalizing the purchase order.

Selection Notes

Select this component when a precise 1 µH inductance is required for RF applications. The 1% tolerance makes it suitable for circuits demanding high accuracy. Consider the 435 mA current rating and 250 mOhm resistance for power handling constraints. The unshielded design requires careful layout consideration to prevent magnetic interference with nearby components.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with different tolerances and current ratings. The 0819-24F specifically targets applications requiring low inductance with high precision. It shares physical dimensions with other variants in the family but differs in electrical performance specifications.

Replacement Considerations

The 0819R-24F is a documented alternative within the same product line. Verify that the R-series variant meets all electrical requirements, including the 1 µH inductance, 435 mA current rating, and 250 mOhm resistance. Ensure mechanical compatibility remains unchanged due to identical package dimensions.
