The component has a maximum DC resistance of 0.4 Ohms and supports a maximum DC current of 890 mA. Key electrical parameters include a minimum Q factor of 30 at 10 MHz and a self-resonant frequency of 75 MHz. The unit measures 6.35 mm in length and 2.41 mm in diameter, suitable for standard PCB mounting.

Fixed Inductors Feature Summary

• Molded construction provides mechanical stability for unshielded RF environments
• Axial lead configuration facilitates through-hole PCB integration
• High current handling capability supports demanding RF circuit loads

Fixed Inductors Applications

• Radio frequency signal processing circuits
• RF choke applications in communication systems
• Impedance matching networks in RF transceivers

Fixed Inductors Procurement Notes

Verify the specific suffix 'G' against the manufacturer's official datasheet to confirm compliance with RoHS directives and material composition requirements. Ensure that the ordering quantity aligns with the manufacturer's standard reel packaging specifications. Confirm that the axial lead dimensions match the target PCB footprint design constraints prior to final procurement authorization.

Fixed Inductors Selection Notes

Select this component when a low-inductance value with high precision is required for RF filtering or chocking. The 2% tolerance ensures stable performance in sensitive signal paths. Verify that the operating frequency range remains below the 75 MHz self-resonant limit to maintain inductive behavior. Consider the 890 mA current rating to prevent saturation during peak load conditions.

Fixed Inductors Part Context

This part belongs to the 1025/R series of fixed RF inductors manufactured by Delevan. The series utilizes a molded core construction to provide consistent electrical characteristics across production batches. These components are specifically engineered for radio frequency applications where unshielded designs are preferred to minimize parasitic coupling effects in dense circuit layouts.

Fixed Inductors Replacement Considerations

Consult the official Delevan cross-reference documentation for verified substitute part numbers within the same series. Ensure any replacement maintains identical inductance, tolerance, and physical package dimensions.
