Procurement Notes

Verify the complete part number against official Knowles Syfer documentation to ensure correct dielectric type, voltage rating, and termination finish. Confirm that the specific suffix matches the required packaging format and moisture sensitivity level for your assembly process. Cross-reference the manufacturer's latest datasheet to validate compliance with current environmental directives and RoHS standards before finalizing procurement orders.

Selection Notes

Select this component when a moderate capacitance value is required within a 1812 footprint for cost-sensitive designs. Ensure the operating voltage remains below the 50 V rating under all transient conditions. Consider the X7R temperature coefficient when designing circuits sensitive to capacitance drift. Verify compatibility with the intended PCB layout constraints and soldering thermal profiles specified by the manufacturer.
