Procurement Notes

Verify the specific manufacturing lot date code upon receipt to ensure compliance with project timelines. Confirm that the M6 thread pitch matches the mounting hardware specifications. Check for any discontinuation notices or lifecycle changes from the manufacturer prior to finalizing procurement plans.

Selection Notes

Select this component when high current handling capability up to 15 A is required alongside significant capacitance. The threaded bushing style is preferred over surface mount options for applications requiring secure mechanical anchoring. Ensure the 500 VDC rating exceeds the peak circuit voltages to maintain reliability.
