1025R-36K

Fixed Inductors Overview

The Delevan 1025R-36K is a fixed, unshielded molded axial leaded inductor designed for through-hole mounting. It features an iron core and provides an inductance of 4.7 µH with a tolerance of ±10%. The component supports a maximum DC current of 239 mA and exhibits a maximum DC resistance of 1.2 ohms. Electrical performance includes a Q value of 45 at 7.9 MHz and a self-resonant frequency of 75 MHz. It operates within a temperature range of -55°C to 105°C and complies with RoHS3 specifications.

Fixed Inductors Feature Summary

• Molded construction with an iron core for stable magnetic properties
• Unshielded design suitable for general-purpose applications
• Axial through-hole termination for standard PCB integration

Fixed Inductors Applications

• RF circuits requiring specific inductance values
• General purpose filtering applications
• Military electronic systems compliant with MIL-PRF-M15305 standards

Fixed Inductors Procurement Notes

Verify the exact ordering suffix against manufacturer documentation to ensure correct packaging configuration. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the DigiKey part number DN7689-ND for accurate distributor identification. Ensure the selected variant matches the required tolerance and current rating specifications.

Fixed Inductors Selection Notes

Select this component when a 4.7 µH inductance with low DC resistance is required for axial mounting. The 239 mA current rating defines the operational limit for continuous duty cycles. Consider the 75 MHz self-resonant frequency to ensure functionality remains within the desired operating band. Verify that the unshielded form factor does not interfere with adjacent components on the layout.

Fixed Inductors Part Context

This part belongs to the 1025R series manufactured by API Delevan. The series is characterized by molded axial inductors utilizing iron cores. These components are widely used in RF and general-purpose electronics where reliable inductance values are necessary. The product line adheres to established military reliability standards.

Fixed Inductors Replacement Considerations

The 1025-36K is documented as a direct substitute. Both variants share identical electrical parameters including 4.7 µH inductance and 1.2 ohm DC resistance. Differences may exist in packaging or specific military qualification levels.
