Procurement Notes

Verify the complete part number including the suffix to confirm specific termination and packaging details. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure storage conditions align with moisture sensitivity level requirements to maintain component reliability during assembly processes.

Selection Notes

Select this component when a compact 1206 footprint is required for high-current EMI filtering applications. The 300 mA current rating suits moderate power line filtering needs. Verify that the 25 VDC rating meets the circuit's maximum operating voltage. Consider the three-terminal design for superior high-frequency performance compared to standard two-terminal capacitors.

Part Context

This component belongs to the Knowles Syfer XT series of surface-mount multilayer ceramic capacitors. The series is engineered for general-purpose applications requiring reliable performance in harsh environments. The 1206J prefix indicates the 1206 case size and X7R dielectric type, distinguishing it from other voltage or capacitance variants within the same product family.
