Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may indicate limited stock or discontinuation notices. Verify current supply status through authorized channels before design finalization. Consider lifecycle management strategies due to potential obsolescence risks associated with discontinued part numbers.

Selection Notes

Select this component when specific low-capacitance values and tight tolerances are required for RF applications. The 0402 footprint suits space-constrained designs. Ensure compatibility with 50 V operating limits and verify thermal requirements against the -55°C to +125°C range. Confirm that silicon capacitor characteristics align with system stability needs compared to alternative dielectric types.
