1025R-76J

Fixed Inductors Overview

The Delevan 1025R-76J is a leaded RF inductor from the 1025/R series. It features molded construction with an iron core and axial termination. The component provides an inductance of 220 µH with a tolerance of ±5%. It has a maximum DC current rating of 52 mA and a maximum DC resistance of 21 Ohms. The self-resonant frequency is specified at 3.8 MHz. Physical dimensions include a diameter of 2.41 mm and a length of 6.35 mm. It is designed for PCB mount applications.

Fixed Inductors Feature Summary

• Molded unshielded coil construction
• Axial leaded termination for through-hole mounting
• Iron core material for stable inductance

Fixed Inductors Applications

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

Fixed Inductors Procurement Notes

Verify the specific manufacturer source, as API Delevan assets may be held by other entities. Confirm RoHS compliance status and lead-free soldering requirements against the latest datasheet. Ensure the ordering quantity matches the factory pack size of 500 units per reel. Check for any established reliability designations if required for the application.

Fixed Inductors Selection Notes

Select this component when a 220 µH inductance with tight 5% tolerance is required for RF applications. The low DC current rating of 52 mA limits suitability to low-power signal paths rather than power supply filtering. The unshielded design requires careful PCB layout to minimize electromagnetic interference with adjacent components.

Fixed Inductors Part Context

This part belongs to the Delevan 1025/R series of fixed RF inductors. The series offers various inductance values within a standardized axial package footprint. These components are designed for general-purpose RF use where compact size and reliable performance are prioritized over high-current handling capabilities.

Fixed Inductors Replacement Considerations

Cross-reference with other 1025R series variants for different inductance values. Verify electrical compatibility with existing circuit parameters before substitution.
