Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm exact tolerance and packaging specifications. Ensure that the procurement documentation explicitly references the RFCS series silicon construction to distinguish it from ceramic or film alternatives. Confirm compliance with required environmental standards prior to finalizing orders.

Selection Notes

Select this component when precise low-value capacitance is required in minimal space. The silicon construction provides superior stability compared to standard dielectrics. Evaluate the 50 V rating against peak circuit voltages. Consider the tight ±0.1 pF tolerance for critical signal integrity requirements in sensitive analog or RF designs.

Part Context

This part belongs to the RFCS series of thin-film silicon capacitors manufactured by Vishay Electro-Films. The series focuses on high-precision passive components suitable for demanding electronic environments. Silicon-based construction allows for consistent electrical characteristics across varying thermal conditions.

Replacement Considerations

Cross-reference with other Vishay RFCS series variants for different capacitance values. Verify pin compatibility and dimensional constraints before substituting with generic equivalents. Ensure any replacement maintains the same silicon technology and tolerance class.
