0819-22K

Overview

The Delevan 0819-22K is an axial leaded RF inductor featuring a molded unshielded construction. It provides an inductance of 820 nH with a tolerance of 3%. The component supports a maximum DC current of 465 mA and exhibits a maximum DC resistance of 220 mOhms. Designed for PCB mounting, it operates within a temperature range of -55°C to +105°C.

Feature Summary

• Molded unshielded coil design for compact integration
• Axial leaded termination style for through-hole mounting
• Ferrite core construction optimized for RF applications

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific manufacturer source, as API Delevan assets have transitioned. Confirm RoHS compliance status and lead material (tin vs. tin/lead) against the latest datasheet, as historical variants differ. Ensure the supplier provides valid traceability documentation for this legacy component series before finalizing orders.

Selection Notes

Select this component when a low-inductance, high-current axial inductor is required for RF circuits. The 820 nH value suits higher frequency applications compared to the microhenry-range parts in the same series. Verify that the 465 mA current rating meets the circuit's peak requirements and that the unshielded nature does not cause interference in dense layouts.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values ranging from nanohenries to millihenries. The 0819-22K specifically targets applications requiring sub-microhenry inductance with moderate current handling capabilities in a standard axial package.

Replacement Considerations

Direct substitutes include other 820 nH axial RF inductors with similar current ratings. Check cross-reference lists for equivalent performance in terms of Q factor and self-resonant frequency if exact replacement is unavailable.
