The T520D227M004AE012 is a surface-mount solid electrolytic capacitor from KEMET's T520 series. It is designed for applications requiring high capacitance, low ESR (Equivalent Series Resistance), and stable electrical characteristics. The capacitor uses a polymer cathode technology, which provides significant advantages over traditional MnO2 capacitors, including lower ESR and improved surge current handling.

Applications

• Power supplies
• DC-DC converters
• Filtering and decoupling circuits
• Solid state drives (SSDs)
• Industrial control systems

Features

• Polymer cathode technology
• Surface mount design
• Low ESR for high-frequency performance
• High capacitance retention
• RoHS compliant

Benefits

• Improved power efficiency because of reduced energy loss due to the low ESR
• Increased reliability and longer life due to the stable polymer cathode
• Smaller footprint on the PCB (Printed Circuit Board) because of high volumetric efficiency
• Stable performance in demanding applications
• Environmentally friendly due to RoHS compliance

Additional Details

The T520D227M004AE012 has a capacitance of 220 uF (microfarads), a voltage rating of 4V (Volts) DC, and an ESR of 12 mOhms. It comes in a EIA standard 7343-31 case size (D case). The typical operating temperature ranges from -55°C to +105°C. The termination finish is typically matte tin. Polymer electrolytic capacitors usually exhibit a non-catastrophic failure mode, characterized by a gradual increase in leakage current rather than a sudden short, enhancing system safety. Additionally, these capacitors are known for their excellent capacitance stability across varying frequencies and temperatures.
