Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Vishay. Procurement is restricted to remaining stock or secondary market sources. Verify part authenticity carefully due to end-of-life status. Check RoHS compliance details in official documentation before integration. Availability is limited and subject to change without notice.

Selection Notes

Engineers should identify active substitutes immediately due to the obsolete status. Consider parameters such as capacitance value, tolerance, voltage rating, and package size when evaluating alternatives. Ensure replacement components meet the same thermal and RF performance requirements for the specific application design.

Part Context

The RFCS series represents Vishay's line of silicon capacitors designed for RF and microwave applications. These components offer superior stability compared to traditional ceramic types in certain high-frequency scenarios. The 0402 package allows for dense PCB layouts in modern electronic devices requiring minimal footprint.
