0819-58F

Overview

The Delevan 0819-58F is a fixed RF inductor featuring an axial leaded package and unshielded molded construction. It provides a nominal inductance of 27 µH with a tight tolerance of ±1%. The component exhibits a maximum DC resistance of 4.7 Ohms and supports a maximum current rating of 100 mA. Designed for through-hole PCB mounting, it utilizes a ferrite core to ensure stable performance within the radio frequency spectrum.

Feature Summary

• Unshielded molded design for standard RF applications
• Axial leaded termination for through-hole mounting
• High precision tolerance for signal integrity

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required DC resistance and current ratings for the target application environment. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when high precision inductance is critical for RF signal paths. The unshielded nature requires careful layout consideration to prevent electromagnetic interference with adjacent components. Verify that the 100 mA current limit aligns with the operational load to avoid saturation or thermal issues during continuous operation.

Part Context

This part belongs to the Delevan 0819 series of fixed inductors, which are characterized by their molded, unshielded construction. The series is designed for general-purpose RF applications requiring reliable axial leaded components. It serves as a specialized passive element within broader electronic systems focusing on frequency control and signal conditioning.

Replacement Considerations

Direct substitutes include other Delevan 0819 series variants such as the 0819-78F or 0819-96F, provided the inductance and resistance values match the circuit requirements. Alternative manufacturers offering similar axial RF inductors must be evaluated for comparable Q-factor and self-resonant frequency characteristics.
