Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct dielectric type and terminal configuration. Confirm RoHS compliance status and specific packaging requirements such as reel or cut tape quantities prior to ordering. Cross-reference datasheet specifications for thermal and electrical limits to match application needs.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete components. The three-terminal design reduces parasitic inductance compared to standard two-terminal capacitors. Ensure the PCB footprint matches the 1206 metric dimensions and that the 100V rating exceeds the maximum circuit voltage under all operating conditions.
