These ultra-high-stability capacitors are suitable for calibration of standards requiring an uncertainty of parts in 107, such as the AH2700A.
The 1408 Standard Capacitor includes three standards: 1 pF, 10 pF, and 100 pF.

It maintains its own stability because it has a self-contained air-bath whose temperature is held constant
