1025R-04G

Fixed Inductors Overview

The Delevan 1025R-04G is a fixed axial leaded inductor from the 1025R series. It features an unshielded molded construction with an iron core, providing an inductance of 220 nH and a tolerance of ±2%. The component has a maximum DC resistance of 140 mΩ and a rated current of 1.04 A. It operates within a temperature range of -55°C to 125°C and exhibits a self-resonant frequency of 75 MHz.

Fixed Inductors Feature Summary

• Molded unshielded design for general-purpose RF applications
• Iron core construction supporting high current handling
• Axial through-hole termination for standard PCB mounting

Fixed Inductors Applications

• RF circuit filtering
• General-purpose signal processing
• High-frequency impedance matching

Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates conflicting data across sources; confirm specific manufacturing lot requirements if operating in regulated environments. Ensure axial lead dimensions match target PCB footprint specifications prior to integration.

Fixed Inductors Selection Notes

Select this component when low inductance values near 220 nH are required alongside high current capacity up to 1.04 A. The tight ±2% tolerance suits precision RF designs where parameter stability is critical compared to standard ±10% variants.

Fixed Inductors Part Context

This part belongs to the Delevan 1025R series of fixed inductors. These components utilize a tubular molded form factor designed for robustness in electronic assemblies. The series offers various inductance options while maintaining consistent physical dimensions for standardized placement processes.

Fixed Inductors Replacement Considerations

Cross-reference with other 1025R series variants such as 1025R-36K or 1025R-20G only if electrical parameters align with circuit requirements. Verify that substitute parts maintain compatible thermal ratings and lead spacing.
