Procurement Notes

Verify the specific suffix codes against official Knowles Syfer documentation to confirm terminal configuration and material specifications. Ensure that the selected variant matches the required current rating and capacitance tolerance for the target application. Cross-reference the datasheet for precise mechanical footprint details to guarantee compatibility with existing PCB layouts and assembly processes.

Selection Notes

Select this component when space constraints require an integrated solution for both signal integrity and EMI reduction. The 1206 form factor offers a balance between current handling capability and board real estate efficiency. Consider the 50 mA continuous current rating to ensure the component can manage the expected load without thermal issues or performance loss in the final design.

Part Context

This part belongs to the Knowles Syfer feed-through capacitor series, which specializes in combining filtering functions with signal transmission capabilities. These components are distinct from standard MLCCs by their internal structure designed to pass current through the center electrode while shunting noise to ground. The series is widely used in applications requiring compact, high-performance filtering solutions.

Replacement Considerations
