0819-28K

Overview

The Delevan 0819-28K is a fixed axial leaded RF inductor with an iron core. It provides a nominal inductance of 1.5 µH and a maximum DC resistance of 0.49 Ohms. The component supports a maximum DC current of 310 mA and achieves a minimum Q factor of 40. Its self-resonant frequency is specified at 150 MHz. The device features a cylindrical molded unshielded construction designed for PCB mounting.

Feature Summary

• Axial leaded construction with cylindrical molded body
• Iron core design for stable RF performance
• Unshielded configuration to minimize size

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF applications

Procurement Notes

Verify the specific tolerance grade, as suffixes like K typically denote 10% tolerance. Confirm RoHS compliance status, as older API Delevan inventory may be non-compliant. Ensure the axial lead length meets your PCB layout requirements before finalizing the order.

Selection Notes

Select this component when a 1.5 µH value is required with a 310 mA current rating. The 150 MHz self-resonant frequency limits suitability to lower RF bands. Compare against the 0819R-28K if surface mount technology is preferred for automated assembly processes.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series utilizes iron cores and offers various inductance values. The 0819-28K represents a specific point within this family, characterized by its 1.5 µH rating and axial lead form factor.

Replacement Considerations

The 0819R-28K serves as a surface mount equivalent within the same product line. Verify that the SMD footprint and electrical parameters match the system requirements before substituting the through-hole version.
