Abstract :
The development of elevated temperature capacitors suitable for use in oil well logging is outlined. A modified version of a military qualified glass dielectric capacitor was designed. Glass-K dielectrics were used because they offer dielectric K factors 100 time higher than the original glass used. The life test performance results are presented. The capacitors can withstand temperatures of 200°C indefinitely and 250°C for up to an hour without degradation. The capacitor performance features are related to current and future application needs
