0819-42F

Overview

The Delevan 0819-42F is a fixed axial leaded RF inductor from the 0819 series. It features an unshielded molded coil design with an inductance of 5.6 µH and a tolerance of ±1%. The component has a maximum DC resistance of 2.8 Ohms and a rated current of 130 mA. It utilizes standard terminals for PCB mounting and operates within a temperature range of -55°C to +105°C.

Feature Summary

• Unshielded molded construction for compact integration
• Axial leaded termination style for through-hole mounting
• High precision inductance tolerance

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing stages

Procurement Notes

Verify RoHS compliance status directly with the manufacturer, as historical data indicates variations within this product line. Confirm that the specific batch matches the required axial lead configuration and molded package dimensions. Ensure the supplier provides official datasheets to validate the 1% tolerance and 130 mA current rating specifications before finalizing procurement.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications. The 5.6 µH value suits specific frequency bands where shielding is not mandatory. Consider the 130 mA current limit and 2.8 Ohm DCR for power handling requirements. Compare against the 0819R-42F if tighter manufacturing tolerances are necessary for the application.

Part Context

This part belongs to the Delevan 0819 series of fixed inductors. These components are characterized by their molded unshielded design and axial leads. The series offers various inductance values tailored for radio frequency environments, providing reliable performance in signal conditioning and filtering tasks.

Replacement Considerations

The 0819R-42F is a confirmed substitute offering identical electrical characteristics but with a tighter 1% tolerance compared to the standard variant.
