- Ultra-high Stability Capacitor
- 10 pF and 100 pF
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 two standards: 10 pF and 100 pF.
It maintains its own stability because it has a self-contained air-bath whose temperature is held constant
