Fixed Inductors Procurement Notes

Verify the specific manufacturer source, as API Delevan assets have been acquired by other entities. Confirm compliance requirements such as RoHS status against the latest datasheet, as historical records vary. Ensure the ordering suffix matches the required packaging format, typically tape and reel for this series. Cross-reference part numbers carefully due to potential legacy naming conventions.

Fixed Inductors Selection Notes

Select this component when a low-inductance value near 2.2 µH is required for RF stages. The 415 mA current rating suits moderate power levels. Consider the unshielded nature regarding nearby magnetic sensitivity. The axial form factor dictates board layout orientation. Verify thermal limits if operating near the upper boundary of the specified range.

Fixed Inductors Part Context

This part belongs to the 1025R series of fixed inductors manufactured by Delevan. These components are characterized by their robust molded construction and axial leads. The series is widely recognized for use in radio frequency environments where stability and compact size are critical. The 1025R-28G represents a specific inductance variant within this established product line.

Fixed Inductors Replacement Considerations

Direct substitutes include the ER1025-04KS for higher current needs or the 1025-26F for similar low inductance values. Check electrical parameters closely before swapping. Physical dimensions are consistent across the 1025 family, aiding mechanical compatibility.
