Additional Details

This specific part, T520D227M004AE006, features a capacitance of 220 uF (microfarads), a voltage rating of 4V (Volts) DC, and an ESR of 6 mOhms. It is housed in a standard EIA 7343-31 case size (D case). The operating temperature range is typically -55°C to +105°C. The termination finish is generally matte tin. Polymer electrolytic capacitors typically exhibit a benign failure mode, meaning they are more likely to experience a gradual increase in leakage current rather than a catastrophic short circuit, which enhances overall system safety and dependability. These capacitors are also known for their good capacitance retention at high frequencies, making them suitable for modern electronic circuits.
