1025R-84F

Fixed Inductors Overview

The Delevan 1025R-84F is a fixed, unshielded molded RF inductor designed for axial through-hole mounting. It features an iron core and offers a nominal inductance of 470 µH with a tight tolerance of ±1%. The component supports a maximum DC current of 36 mA and exhibits a maximum DC resistance of 42 ohms. Electrical performance includes a minimum Q factor of 50 at 2.5 MHz and a self-resonant frequency of 25 MHz. It operates within a temperature range of -55°C to +105°C and complies with RoHS3 standards.

Fixed Inductors Feature Summary

• Molded construction with an iron core for stable RF performance
• High precision ±1% inductance tolerance
• Established reliability for demanding environments
• Axial leaded package suitable for PCB mounting

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing stages
• Communication equipment modules

Fixed Inductors Procurement Notes

Verify the specific suffix 'F' indicates the required ±1% tolerance level, as standard variants may differ. Confirm RoHS3 compliance status against project requirements. Ensure the axial lead length matches the target PCB layout dimensions. Validate that the 42-ohm DC resistance does not exceed circuit power loss constraints.

Fixed Inductors Selection Notes

Select this component when high inductance stability and precise tolerance are critical for RF applications. The 470 µH value suits low-frequency filtering or energy storage needs. Consider the 36 mA current rating to prevent saturation. The unshielded design requires careful placement to minimize electromagnetic interference with adjacent components.

Fixed Inductors Part Context

This part belongs to the Delevan 1025/R series of molded RF inductors. These components are characterized by their robust construction and consistent electrical properties across wide temperature ranges. The series is widely used in military and industrial electronics where reliability is paramount.

Fixed Inductors Replacement Considerations

Direct substitutes include other 470 µH axial RF inductors with ±1% tolerance and similar current ratings. Verify that alternative parts match the 42-ohm DCR and 25 MHz self-resonant frequency limits to maintain circuit performance.
