KEMET A798D477M2R5ATE009

A798 series high humidity and high temperature solid state polymer aluminium organic capacitors (AO-CAP). The cathode is a conductive organic polymer which results in very low ESR and improved capacitance retention at high frequency. AOCAPs may be operated at steady state voltages up to 100% of rated voltage without the need to de-rate. Since there is no liquid electrolyte, the A798 offers long operational lifetimes, low ESR and high operational temperatures. The small package size, high ripple current capability, high operating temperature, low parasistics and capacitance stability over life span makes the A798 ideal for demand applications. 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. Typical applications include DC/DC converters, notebook PCs, telecommunications, displays, and industrial applications with harsh humidity and temperature requirements.
