Procurement Notes

Verify the specific suffix MX0 against official manufacturer documentation to confirm exact tolerance and sealing specifications. Ensure compatibility with existing PCB layouts regarding the 3.29 mm length and 3.25 mm diameter dimensions. Confirm that the 500 VDC rating and 5 A current handling meet the system requirements. Cross-reference the X7R dielectric characteristics with thermal management plans for operation between -55°C and +125°C.

Selection Notes

Select this component when a compact, high-voltage feedthrough solution is required for EMI suppression. The 2.2 nF capacitance value suits specific filtering needs within the SFSWR series. Consider the bottom end seal design if mechanical stability during soldering is critical. Evaluate the 5 A current rating against peak load conditions to ensure reliable operation without degradation.
