GORE™ High Temperature Capacitors for Oil & Gas Power Electronics

GORE High Temperature Capacitors reduce the risk of tool failure by delivering stable performance in harsh oil and gas downhole environments. Unlike traditional capacitors, Gore’s technology avoids sudden and complete failure for a more predictable mission completion.

Endurance testing of 111 Gore capacitors at maximum operational ratings indicates 90% probability of capacitance performance. When considering an electronic system design that requires a minimum 80% starting capacitance to operate with stability, at least 95% of GORE™ capacitors will pass at 1000 hours and at least 91% at 1500 hours (95% confidence levels). For actual operating conditions below the maximum ratings, expectations of capacitor longevity can be substantially extended.

Traditional capacitors require substantial de-rating to meet the need for high capacitance and high voltage in high-temperature conditions. So, design engineers have to use large amounts of small capacitors, which can complicate system design, cause numerous potential failure points, and increase installation costs.

Alternatively, a single Gore capacitor offers a large amount of stable capacitance with minimal de-rating under high temperature and voltage conditions.
