0819-04H

Overview

The Delevan 0819-04H is an axial leaded RF inductor featuring a molded unshielded coil construction. It provides an inductance of 150 nH with a tolerance of 3%. The component supports a maximum DC current of 760 mA and exhibits a maximum DC resistance of 180 mOhms. Designed for PCB mounting, it utilizes standard axial terminals and operates within the RF application spectrum.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial leaded termination style for through-hole mounting
• High current handling capability up to 760 mA

Applications

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

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 historical data varies. Ensure the axial package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-inductance value near 150 nH is required for high-frequency circuits. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Verify that the 760 mA current rating exceeds the peak operational current of the target application.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series is characterized by molded epoxy bodies and axial leads, offering a compact solution for radio frequency designs. The 0819-04H specifically targets applications requiring precise low-value inductance with moderate current capacity.

Replacement Considerations

Cross-reference with other 150 nH axial RF inductors from manufacturers such as Coilcraft or Bourns if supply constraints exist. Ensure replacement parts maintain similar Q-factor and self-resonant frequency characteristics to preserve circuit performance.
