High-Temperature Aluminum Polymer Organic Capacitors – A798 Series

KEMET high-humidity and high-temperature solid-state capacitors offer a long operational lifetime

Image of Kemet High-Temperature Aluminum Polymer Organic Capacitors – A798 SeriesKEMET, a YAGEO Company, offers aluminum organic capacitor (AO-CAP) solid-state capacitors for a wide range of applications. The cathode is a conductive organic polymer, which results in very low ESR and improved capacitance retention at high frequency. AO-CAPs may be operated at steady-state voltages up to 100% of rated voltage without the need to derate. Since there is no liquid electrolyte, the A798 offers long operational lifetimes, low ESR, and high operational temperatures. Enhancements to the design and selected material upgrades were introduced to deliver 1,000 hours at +85°C/85% RH rated voltage and +125°C endurance life and storage.

Features
  • Minimum ESR up to 3 mΩ
  • Polymer cathode technology
  • High-frequency capacitance retention
  • Non-ignition failure mode
  • 100% accelerated steady-state aging
  • 100% surge current tested
  • Volumetric efficiency
  • Self-healing mechanism
  • EIA standard case sizes
Applications
  • DC/DC converters
  • Notebook PCs
  • Telecommunications
  • Displays
  • Industrial applications with harsh humidity and temperature requirements
