1025R-74K

Fixed Inductors Overview

The Delevan 1025R-74K is a fixed RF inductor designed for through-hole mounting. It features an axial leaded package with unshielded construction and a ferrite core material. The component provides an inductance of 330 nH with a tolerance of ±10%. It supports a maximum DC current of 830 mA and has a maximum DC resistance of 0.22 Ohms. The self-resonant frequency is specified at 410 MHz, ensuring performance in high-frequency applications.

Fixed Inductors Feature Summary

• Unshielded axial leaded construction for standard PCB mounting
• Ferrite core material optimized for RF signal integrity
• High self-resonant frequency capability for broadband use

Fixed Inductors Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing stages

Fixed Inductors Procurement Notes

Verify the specific suffix requirements against the manufacturer's latest documentation to ensure compliance with military or commercial standards. Confirm that the axial lead dimensions match the target PCB footprint before finalizing procurement orders. Check for RoHS status variations as this series may have non-compliant variants.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 330 nH is required for RF applications. Ensure the operating current does not exceed 830 mA to prevent saturation. Consider the unshielded design regarding potential electromagnetic interference with nearby components in dense layouts.

Fixed Inductors Part Context

This part belongs to the 1025R series of RF inductors manufactured by API Delevan. The series is characterized by established reliability and is often associated with MIL-PRF-39010 specifications. These components are widely used in aerospace and defense electronics requiring stable passive components.

Fixed Inductors Replacement Considerations

Direct substitutes include other 330 nH axial RF inductors from manufacturers such as Coilcraft or Bourns, provided they meet the 830 mA current rating and 410 MHz self-resonant frequency constraints. Verify physical size compatibility.
