Additional Details

The T520D227M004AE065 features a capacitance of 220 uF (microfarads), a voltage rating of 4V (Volts) DC, and an ESR of 65 mOhms. It is housed in a EIA standard 7343-31 case size (D case). The operating temperature range typically spans from -55°C to +105°C. The termination finish is usually matte tin. Polymer electrolytic capacitors typically exhibit a benign failure mode, meaning that instead of a sudden short circuit, they tend to fail with a gradual increase in leakage current, which improves the overall safety and predictability of the system. The T520 series capacitors are known for their capacitance stability across a range of temperatures and frequencies.
