CAP-XX expanded its product line with the High Temperature HS and HW series supercapacitors which feature a higher-boiling-point electrolyte that extends operating and storage temperature from 75°C to 85°C, and operating voltage (V) from 4.5V to 5.5V. These supercapacitors work reliably in devices where nearby components can get very hot, such as RF Power Amplifiers, which can reach 120°C during transmission, as well as in devices which are exposed to environmental high temperatures, such as a mobile phone left on the dashboard of a car in direct sunlight, or in the engine compartment in an automotive application. They offer long-life performance at up to 2.75V in single-cell versions, and 5.5V in dual-cell versions with the two cells connected in series. All devices operate from -40°C to +85°C.
