Procurement Notes

Verify the manufacturer part number against official Vishay documentation to ensure authenticity. Confirm that the specific suffix matches the required voltage rating and tolerance specifications for your design. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a precise 12 pF capacitance is required in a minimal 0402 footprint. Ensure the operating frequency aligns with the silicon capacitor's performance characteristics. Verify that the 16 V rating exceeds the peak voltage in the target circuit to maintain reliability.

Part Context

This part belongs to the RFCS series of silicon RF capacitors from Vishay Electro-Films. These components are engineered for radio frequency applications where standard ceramic capacitors may exhibit undesirable parasitic inductance or capacitance drift at high frequencies.

Replacement Considerations

Cross-reference with other Vishay RFCS variants or equivalent silicon capacitors from manufacturers like Murata or Samsung Electro-Mechanics. Ensure replacement parts match the 12 pF value, ±5% tolerance, and 0402 package dimensions.
