Additional Details

The T520D227M004ATE025 features a capacitance of 220 uF (microfarads), a voltage rating of 4V (Volts) DC, and an ESR of 25 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 typically matte tin. The use of polymer electrolytic technology results in a benign failure mode, which can lead to increased system safety and prevent abrupt circuit failures. Polymer capacitors are also known for having better capacitance retention at higher frequencies as compared to other capacitor technologies. This makes them well-suited for modern high-frequency electronic circuits.
