Procurement Notes

Verify the specific terminal configuration and current rating against circuit requirements before integration. Confirm that the 50 mA current handling capability aligns with operational loads. Ensure the 1812 footprint matches the PCB layout constraints. Cross-reference the X7R characteristics with thermal stability needs.

Selection Notes

Select this component when integrated EMI filtering is required without additional discrete inductors. The feed-through design simplifies layout compared to standard MLCCs. Evaluate the trade-off between the X7R dielectric's higher capacitance density and its non-linear voltage coefficient against C0G alternatives.

Part Context
