Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Delevan documentation to ensure compatibility with system requirements. Confirm that the RoHS3 status aligns with environmental regulations for the target deployment region. Check for any military or reliability certifications if the application demands strict adherence to MIL-PRF standards.

Fixed Inductors Selection Notes

Select this component when a 2.2 mH inductance with a 68 mA current rating is required. Ensure the physical dimensions of 6.10mm diameter by 18.80mm length fit the available board space. Consider the 30 Ohm DC resistance impact on circuit efficiency and verify that the 2 MHz self-resonant frequency meets the operational bandwidth needs.

Fixed Inductors Part Context

This inductor belongs to the 2500(R) series manufactured by Delevan. It shares the same physical form factor and mounting style as other components within this family, such as the 2500R-44K, while differing in electrical specifications like inductance and current handling capabilities.
