Fixed Inductors Procurement Notes

Verify compliance with specific military standards such as MIL-PRF-M15305 or MS75084 if required by the application. Confirm RoHS status and environmental certifications prior to procurement. Ensure the selected packaging option aligns with assembly line requirements. Cross-reference datasheet parameters against system constraints to validate electrical suitability.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required for low-frequency RF applications. The 150 µH rating and 61 mA current limit define the operational envelope. Consider the 15 Ohm DC resistance impact on circuit efficiency. The 11 MHz self-resonant frequency sets the upper operational boundary for effective inductive behavior.

Fixed Inductors Part Context

This part belongs to the 1025R series of fixed inductors manufactured by Delevan. The series offers various inductance values tailored for RF environments. The 1025R-72F represents a higher inductance variant within the lineup, distinguished by its specific 150 µH rating and associated current handling capabilities compared to lower-value counterparts.

Fixed Inductors Replacement Considerations

Equivalent parts include the 1025-72F and DN2572 variants. Verify that substitute components match the 150 µH inductance, 15 Ohm DCR, and 61 mA current rating. Ensure physical dimensions and axial lead configuration remain compatible with existing board layouts.
