Procurement Notes

Verify the specific suffix 'DBTTS' against official Vishay documentation to confirm tape-and-reel packaging configuration. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Ensure the component meets the required operating temperature range for the target application environment before finalizing procurement.

Selection Notes

Select this component when a precise sub-picofarad capacitance value is required for RF tuning. The 0402 package size supports high-density PCB layouts. Consider the 100 ppm/°C temperature coefficient for stability requirements across varying thermal conditions. Validate that the high Q characteristic aligns with the low-loss requirements of the specific RF system design.

Part Context

This part belongs to the RFCS series of silicon capacitors from Vishay Electro-Films. These components are designed to replace traditional ceramic capacitors in RF applications where superior stability and lower parasitic inductance are critical. The series provides reliable performance in high-frequency environments.

Replacement Considerations

Consult official Vishay substitution guides for direct equivalents. Verify pin compatibility and electrical parameters if considering alternative manufacturers.
