- High-frequency signal coupling and decoupling
Procurement Notes
This component is classified as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors or verifying specific stock status through authorized channels. Designers should consider lifecycle implications and potential supply chain disruptions when planning production.
Selection Notes
Select this part only if the 1.5 pF capacitance and 0402 package align with the design requirements. Due to its obsolete status, verify long-term availability and lead times carefully. Ensure the 50 V breakdown voltage meets the circuit's operational limits and that the high Q characteristic is necessary for the specific RF application.
Part Context
The RFCS series represents Vishay's silicon capacitor line, offering alternatives to traditional ceramic capacitors in RF applications. These components provide consistent performance across temperature variations and are designed for high-frequency stability. The RFCS04021500CBTT1 specifically targets niche RF needs within the compact 0402 form factor.
Replacement Considerations
As an obsolete part, direct substitutes are not officially confirmed. Evaluate other RFCS series variants with similar capacitance and package size, such as RFCS04026000DBTT1, ensuring electrical parameters match the original design intent.
