Procurement Notes

Verify the specific MXTE03 suffix configuration against official datasheets to ensure correct pinout and termination specifications. Confirm RoHS3 compliance status prior to integration. Check for lead-free solderability requirements. Validate that the 50 mA current rating meets system thermal constraints. Ensure the 1812 footprint matches the target PCB layout dimensions.

Selection Notes

Select this component when high-voltage filtering is required in a compact surface-mount form factor. The flexible terminals make it suitable for applications subject to mechanical stress. Compare electrical parameters against standard MLCCs if board flex resistance is not a primary design constraint. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.
