Procurement Notes

Verify the specific voltage rating variant required for the application, as sources indicate both 50 V and 70 V ratings for this part number. Confirm that the 10 A current capacity aligns with the system's peak load requirements. Ensure the axial bushing dimensions match the chassis mounting hole specifications. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when high capacitance is needed for low-frequency noise attenuation alongside moderate current handling capabilities. The bushing style is suitable for applications requiring robust mechanical grounding through the chassis. Consider the operating temperature range to ensure stability under thermal stress. Compare insertion loss specifications against other feedthrough capacitors if higher frequency rejection is necessary.
