Procurement Notes
Verify the exact physical dimensions and mounting hole specifications against your panel design requirements before procurement. Confirm that the axial bushing termination style matches your assembly process. Ensure the 500V DC rating and 0.22 µF capacitance align with your circuit's electrical demands. Check for any specific RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a panel-mount feedthrough filter is required for EMI suppression. The axial bushing style facilitates direct chassis or panel integration. Consider the X7R dielectric characteristics for general-purpose stability. Verify that the 500V DC rating provides sufficient margin for your application's peak voltages. Compare physical size constraints against available panel space.
