1025R-84G

Fixed Inductors Overview

The Delevan 1025R-84G is a fixed RF inductor designed for leaded mounting applications. It features an unshielded molded coil construction with an iron core, suitable for general-purpose and radio frequency circuits. The component exhibits a nominal inductance of 470 µH with a tight tolerance of ±2%. It has a maximum DC resistance of 42 ohms and supports a rated current of 39 mA. The device operates within a temperature range of -55°C to +105°C and utilizes axial leads for PCB integration.

Fixed Inductors Feature Summary

• Unshielded molded coil design for RF applications
• Axial leaded package for through-hole mounting
• Iron core construction for stable inductance

Fixed Inductors Applications

• Radio frequency signal processing
• General purpose filtering circuits
• Impedance matching networks

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation when sourcing, as API Delevan and Delevan are associated with this series. Confirm that the unshielded variant matches the circuit requirements, as shielded alternatives exist within the same product family. Ensure axial lead dimensions align with the target PCB layout before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when high inductance values are required in a compact axial form factor. The 42-ohm DC resistance limits current handling to approximately 39 mA, making it unsuitable for power supply filtering. Verify that the unshielded nature does not cause electromagnetic interference issues in dense layouts compared to shielded options.

Fixed Inductors Part Context

This part belongs to the 1025R series of fixed RF inductors manufactured by Delevan. The series offers various inductance values ranging from low microhenries to hundreds of microhenries. Variants differ by shielding status, tolerance, and current ratings, allowing designers to choose between shielded and unshielded configurations based on noise sensitivity.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1025R series variants with similar inductance but different tolerances or shielding. Cross-reference with API Delevan catalogs for equivalent unshielded parts. Ensure replacement components maintain the same axial lead spacing and physical envelope to fit existing footprints.
