Procurement Notes

Verify the specific suffix 'TT1' against the manufacturer's current datasheet to confirm packaging details such as cut tape or reel specifications. Ensure compliance with RoHS3 standards if required by your assembly process. Cross-reference the part number with official Vishay documentation to confirm availability status, as electronic components may undergo lifecycle changes or obsolescence notices without immediate public announcement.

Selection Notes

Select this component when a small form factor is required for high-frequency applications. The 0402 package allows for dense PCB layouts. Consider the 100 PPM/°C temperature coefficient for environments with significant thermal variations. The 25 V rating should be sufficient for most low-power RF signals. Verify that the 8.2 pF value aligns with the target resonant frequency or impedance requirements of the circuit design.
