Procurement Notes

Verify the specific suffix E03 against official datasheets to confirm terminal configuration and termination material compatibility. Ensure the selected variant matches the required current rating and voltage derating curves for the target application environment. Cross-reference manufacturer documentation for any updates regarding RoHS compliance or material declarations prior to final procurement decisions.

Selection Notes

Select this component when space-constrained designs require superior high-frequency attenuation compared to standard two-terminal capacitors. Evaluate the trade-off between the larger footprint required for three-terminal structures and the resulting improvement in parasitic inductance reduction. Confirm that the 200V DC rating provides adequate margin for the peak transient voltages present in the specific circuit node.

Part Context

This part belongs to the Knowles Syfer MLCC family, specifically engineered for reliability in demanding environments. The 1206J series designation indicates a standard 1206 case size with J representing the capacitance tolerance code. As a feed-through type, it differs from conventional parallel-plate capacitors by utilizing a central conductor pass-through structure.
