High Q factor suitable for high-frequency applications
Compact 0402 surface-mount footprint

Applications

RF circuit filtering
Impedance matching networks
High-frequency signal coupling

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by the producer. Verification of availability requires checking distributor end-of-life inventory or authorized secondary market sources. Designers must confirm current stock status and lead times through specific suppliers before integration into new production cycles.

Selection Notes

Select this part for applications requiring precise small-value capacitance in RF environments. Ensure the design accommodates the 0402 package dimensions and the specified 50 V breakdown rating. Verify that the operating temperature range aligns with system requirements and consider the component's obsolescence status for long-term supply chain stability.

Part Context

The RFCS series represents Vishay’s line of silicon capacitors designed for radio frequency applications. These components offer superior stability compared to traditional ceramic types at high frequencies. The 0402 variant provides a compact solution for space-constrained PCB layouts while maintaining consistent electrical characteristics across varying environmental conditions.
