Procurement Notes

This component is officially obsolete and no longer manufactured by Vishay Electro-Films. Verification of availability should focus on authorized distributors holding remaining stock or approved substitute part numbers. Ensure that any replacement components meet the original electrical specifications and physical footprint requirements to maintain design integrity.

Selection Notes

Selection requires identifying equivalent silicon capacitors with matching 2.2 pF capacitance, 50 V rating, and 0402 package dimensions. Verify that alternative parts support the required ±5% tolerance and operate within the -55°C to +125°C range. Cross-reference datasheets to confirm compatibility with existing RF circuit designs and mounting processes.

Part Context

The RFCS04022200CJTT1 belongs to the RFCS series of silicon capacitors, which are engineered for radio frequency applications. This specific model represents a low-capacitance variant suitable for high-frequency circuits where small form factors and precise capacitance values are critical for performance stability.
