0819-20F

Overview

The Delevan 0819-20F is a fixed axial leaded RF inductor with a nominal inductance of 680 nH and a tolerance of 1%. It features a molded unshielded coil construction, a maximum DC resistance of 200 mOhms, and a rated current of 485 mA. Designed for PCB mounting, this component operates within a temperature range up to 105 °C and utilizes standard terminations.

Feature Summary

• Molded unshielded coil construction for general-purpose RF applications
• Axial leaded termination style suitable for through-hole PCB mounting
• Iron core material providing stable inductance characteristics

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose inductive components

Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status and lead content details against the official datasheet, as historical data may vary. Ensure the ordering suffix matches the required tolerance and packaging specifications for your production requirements.

Selection Notes

Select this component when a low-inductance value near 680 nH is required with tight 1% tolerance. The unshielded design necessitates careful layout consideration to prevent magnetic coupling with adjacent traces. Verify that the 485 mA current rating meets the peak load requirements of the target circuit.

Part Context

This part belongs to the Delevan 0819 series of molded RF inductors. The series offers various inductance values with different tolerance codes, typically indicated by the final letter in the part number. These components are designed for high-frequency applications where compact size and reliable performance are prioritized.

Replacement Considerations

The 0819-20H serves as a direct substitute with identical electrical parameters but a 3% tolerance instead of 1%. Other variants in the 0819 series may be considered if different inductance or current ratings are acceptable.
