Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official API Delevan documentation. Confirm that the specific ordering suffix matches the required tolerance and packaging configuration. Ensure compliance with RoHS status requirements as indicated in the datasheet. Validate physical dimensions against schematic constraints prior to procurement to ensure proper fitment on the target printed circuit board.

Selection Notes

Select this component when a 160 µH inductance value is required with a 126 mA current limit. The unshielded nature necessitates careful layout planning to minimize electromagnetic interference coupling with adjacent traces. Verify that the operating environment temperature range aligns with the component's specified limits. Consider the axial form factor for manual or automated insertion processes compatible with the specified package dimensions.

Part Context

This part belongs to the Delevan ER1537 series of established reliability inductors. These components are manufactured according to MIL-PRF-39010 specifications, ensuring consistent performance for rugged applications. The series offers various inductance values within a standardized physical footprint, facilitating design flexibility while maintaining mechanical compatibility across different circuit designs requiring axial leaded inductors.

Replacement Considerations

Direct substitutes must match the 160 µH inductance, 126 mA current rating, and 6.4 Ohm DC resistance. Compatible alternatives should maintain the axial package dimensions of 9.53 mm x 3.96 mm. Verify that any replacement part adheres to similar MIL-PRF-39010 reliability standards if used in critical systems.
