• Offers power line filtering functionality for VCC circuits
• Utilizes a compact surface-mount form factor for space-constrained designs

Applications

• EMI suppression in electronic systems
• Broadband I/O filtering
• VCC power line filtering

Procurement Notes

Verify the specific capacitance tolerance requirements against the datasheet specification of -20% to +80%, as this differs from standard symmetric tolerances. Confirm that the X5R dielectric characteristics align with the thermal stability needs of the application environment. Ensure the 100 VDC rating meets the circuit's maximum operating voltage. Check compatibility with the specified 0805 (2012 metric) footprint dimensions during PCB layout verification.

Selection Notes

Select this component when EMI suppression is required for low-capacitance signal lines or power rails. The X5R dielectric offers higher volumetric efficiency compared to C0G/NP0 types but exhibits greater capacitance variation with voltage and temperature. Consider the 600 mOhm maximum DC resistance for current handling limits. The four-terminal design facilitates effective grounding paths for improved high-frequency performance in filter configurations.

Part Context

This part belongs to the W2F series of multilayer ceramic SMD feedthrough capacitors from KYOCERA AVX. These components are designed specifically for electromagnetic interference suppression. The series provides solutions for filtering noise on data lines and power supplies in compact electronic assemblies. The W2F designation indicates a two-terminal filter capacitor configuration within the broader product family.

Replacement Considerations

W2F11A2208AT1A is a parameter-equivalent alternative with 22 pF capacitance.
