Procurement Notes
Verify the specific suffix TWS against official datasheets to confirm packaging type and tape specifications. Ensure compatibility with standard SMT reflow profiles. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and RoHS compliance status prior to integration into production schedules.
Selection Notes
Select this component for applications requiring precise small-value capacitance in RF environments. The 0.3 pF value and tight tolerance make it suitable for high-frequency tuning. Consider the 0402 package size for board density constraints and verify thermal stability requirements against the specified operating temperature range.
Part Context
This component belongs to the RFCS series of silicon capacitors from Vishay Electro-Films. These parts are designed to replace traditional ceramic capacitors in RF applications where parasitic inductance and temperature stability are critical concerns. The series offers improved consistency over wide frequency ranges compared to conventional dielectric materials.
Replacement Considerations
Direct substitutes include RFCS04021200DBTWS and RFCS04024000DBTWS for different capacitance values within the same series. Verify pinout and dimensional compatibility when considering alternative manufacturers' silicon capacitors.
