Procurement Notes

Verify the specific suffix CK against official NXP documentation to confirm the exact electrical characteristics, such as resistance and capacitance values, prior to integration. Ensure compatibility with existing PCB footprint requirements and validate that the component meets all relevant environmental standards required for the target application environment.

Selection Notes

Select this component when a compact solution combining ESD protection and low-pass filtering is required for high-speed signal lines. Consider the trade-off between insertion loss and attenuation performance relative to the specific frequency range of the application. Evaluate the thermal and mechanical constraints of the 3-XQFN package to ensure adequate board space and mounting reliability.

Part Context

This part belongs to the PEMI1 series of EMI/RFI filters from NXP, which are designed for protecting sensitive inputs against transient events while attenuating high-frequency noise. The series offers various impedance and capacitance combinations tailored for different signal integrity requirements across automotive and industrial sectors.

Replacement Considerations

Consult NXP datasheets for alternative suffixes within the PEMI1 family that offer different resistance or capacitance values if the CK variant does not meet specific circuit impedance matching needs.
