1025R-78J

Fixed Inductors Overview

The Delevan 1025R-78J is a fixed, unshielded molded inductor designed for through-hole mounting. It features an axial package with dimensions of 0.095 inches diameter by 0.250 inches length (2.41mm x 6.35mm). The component provides an inductance of 270 µH with a maximum DC resistance of 25 Ohms and a rated current of 47 mA. It exhibits a minimum Q factor of 30 and a self-resonant frequency of 8 MHz.

Fixed Inductors Feature Summary

• Unshielded molded construction utilizing ferrite core material
• Axial lead termination style suitable for PCB mounting
• Established reliability performance characteristics

Fixed Inductors Applications

• RF circuit filtering applications
• General purpose inductive components
• Signal processing circuits

Fixed Inductors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and testing frequencies. Confirm RoHS compliance status as historical data indicates non-compliance for similar series variants. Ensure procurement channels provide valid traceability records for established reliability requirements.

Fixed Inductors Selection Notes

Select this component when a 270 µH inductance value is required with a low current rating of 47 mA. The high DC resistance of 25 Ohms limits suitability for power supply filtering; it is optimized for signal integrity and RF impedance matching. Verify that the 8 MHz self-resonant frequency aligns with the target operating bandwidth.
