Increase downhole tool reliability with the only capacitor offering stable performance in harsh environments. Unlike traditional capacitors, Gore technology avoids sudden and complete failure for a more predictable mission completion. Film Capacitors for Oil & Gas Power Electronics rated to 200°C, 400 VDC. Datasheet includes overview, benefits, properties, test data, and example configurations. Power electronics in oil and gas downhole tools are subjected to some of the harshest operating conditions on the planet. Design teams have had to work around the challenges of legacy capacitor technologies: using multiple capacitors to meet power needs while overcoming de-rating, innovating specialty mounting techniques for shock & vibration, the use of dewar insulation systems, or even cooling systems to resist extreme temperatures. But despite the number of incremental improvements, the critical weakness is hidden in the failure mode of traditional capacitor choices. For when they fail, they fail short leading to risk of downhole tool failure. 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).
