Procurement Notes

This component is officially obsolete and no longer manufactured. Verification of availability requires checking distributor inventory for remaining stock or identifying approved substitutes. Procurement should focus on compatible replacement part numbers rather than original supply chains.

Selection Notes

Selection is constrained by the obsolete status of this specific part number. Engineers must evaluate alternative silicon capacitors from the same series or different manufacturers that match the required 22 pF capacitance, 0402 footprint, and 10 V rating while ensuring compliance with RoHS3 standards.

Part Context

The RFCS04022200BJTT1 belongs to the RFCS series of silicon capacitors. These components are designed to replace traditional ceramic capacitors in RF applications where size and stability are critical. The series offers consistent performance across wide temperature ranges suitable for demanding electronic environments.
