Capacitor Life 
HyCap-HT capacitors can withstand either 175°C or 200°C life test with appropriate voltage (see table on datasheet) for durations of 500–2000 hours dependent on P/N. Details available upon request.

Design Challenge

In specific disciplines of downhole instrumentation,  high-energy capacitors are essential to achieve optimal energy density, endure intense shock and vibration,  and ensure reliable, long-lasting performance  even in extreme temperatures ranging from -20°C  to 150°C, 175°C, and 200°C.

Our Solution

Quantic™ Evans HyCap-HT capacitors integrate the exceptional performance of a ruthenium oxide cathode, tantalum anode, and tantalum pentoxide dielectric. These capacitors excel in energy storage, offering the utmost energy density per unit volume. They are particularly well-suited for oil and gas applications, as they can reliably operate in temperatures reaching 200°C, even in harsh conditions involving intense shock and vibration.
