1025R-28J

Fixed Inductors Overview

The Delevan 1025R-28J is a fixed, unshielded RF inductor from the 1025R series. It features an axial leaded package with molded construction and an iron core. The component has an inductance of 2.8 µH with a ±5% tolerance. It supports a maximum DC current of 340 mA and exhibits a maximum DC resistance of 1.6 ohms. The Q factor is rated at 40 when tested at 7.9 MHz, with a self-resonant frequency of 100 MHz. Operating temperature ranges from -55°C to 105°C.

Fixed Inductors Feature Summary

• Molded unshielded coil design for consistent RF performance
• Axial through-hole termination style for standard PCB mounting
• Iron core material providing stable inductance characteristics

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• General purpose inductive applications

Fixed Inductors Procurement Notes

Verify the specific suffix 'J' indicates the required ±5% tolerance level against your schematic requirements. Confirm that the axial lead length and body dimensions fit within the designated footprint on the target printed circuit board layout prior to finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a 2.8 µH inductance value is required with tight ±5% tolerance. Ensure the application current does not exceed the 340 mA rating to prevent thermal issues. Consider the 1.6 ohm DC resistance impact on signal loss if used in low-loss RF paths.

Fixed Inductors Part Context
