| Zusammenfassung | Gas-dielectric standard capacitors have a temperature coefficient of (0 ± 2) μF/F per K. This is too high for deriving the capacitance unit from the quantum Hall resistance. A standard capacitor was thermally controlled to reduce by two orders of magnitude its temperature variation. The construction details and the experimental results are discussed. |
