Fixed Inductors Procurement Notes

Verify the specific suffix 'R' indicates bulk packaging when ordering. Confirm RoHS compliance status as it varies by manufacturer batch or series revision. Ensure the required current rating of 144 mA aligns with the target circuit load to prevent saturation. Cross-reference the DigiKey part number DN7695-ND for accurate distributor availability and lead times.

Fixed Inductors Selection Notes

Select this component for circuits requiring a 22 µH inductance with moderate current handling capabilities. The axial form factor is ideal for prototyping or low-volume production where manual insertion is feasible. Consider the 3.3 ohm DC resistance impact on voltage drop. Verify that the 25 MHz self-resonant frequency meets the operational bandwidth requirements of the application.

Fixed Inductors Part Context

This part belongs to the 1025R series of fixed inductors manufactured by API Delevan. The series offers various inductance values tailored for RF and general electronic applications. The 1025R-52K specifically represents the 22 µH variant within this lineup, sharing common physical dimensions and mounting characteristics with other members of the family.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include the 1025-52K, which shares identical electrical parameters but differs in packaging (Tape & Reel vs Bulk) and RoHS compliance status. The ER1025-52KP is another alternative with similar specifications but may have different reliability classifications.
