Tantalum - Polymer Capacitors

The T550B687M008AT4251 is a type of tantalum - polymer capacitor, a device used to store electrical energy. This capacitor is a wet electrolytic type of tantalum capacitor, a device that uses a conductive polymer as the dielectric. Wet electrolytic capacitors can have either a single or double layer construction, with each layer made of a dielectric layer and an electrolyte. The dielectric layer is typically made of a solid or semi-solid material, such as metal, ceramic, or polyester, while the electrolyte is a liquid suspension of metal ions that helps to transfer charge.

The T550B687M008AT4251 is made up of a sintered anode core and a sintered cathode core bonded with a polymer dielectric. The anode and cathode cores are made of either a metal or ceramic, while the dielectric layer is typically made of a solid polymer or a polymer blend. This type of capacitor is typically used to store high voltage and high current, such as in power conversion applications such as rectifiers, inverters, amplifiers, and other energy devices. It can also be used in power supplies, motors, digital signal converters, and RF circuits.

The T550B687M008AT4251 is typically rated at a voltage of up to 50 volts, and a current of up to 310 mA. It is available in a variety of sizes, with a range from 0603 to 2220, and has an operating temperature range of -55°C to +125°C. This type of capacitor has a variety of features that make it an ideal choice for applications requiring high capacitance, low ESR, and low leakage.

The working principle of this type of capacitor is based on the physical movement of ions within the electrolyte solution. When a voltage is applied to the capacitor, the ions move from one side of the electrode to the other, creating an electrical current in the process. This electrical current creates a charge on the plates of the capacitor, which then creates an electric field between them. This electric field produces a voltage that is stored within the capacitor, allowing it to function as an energy storage device.

Tantalum - polymer capacitors like the T550B687M008AT4251 are ideal for applications requiring high capacitance, low ESR, and low leakage due to the physical properties of the dielectric. They are also highly resistant to mechanical shock and vibration, which makes them suitable for applications where physical environment is a factor. Additionally, these capacitors can be used in both high frequency and high voltage circuits, giving designers a wide range of options for their power-supply designs.

The T550B687M008AT4251 is commonly used in automotive, medical, telecommunications, and industrial applications, due to its high-performance characteristics and its ability to operate over a wide range of temperatures and frequencies. It is also an ideal choice for applications in military, aircraft, and unmanned systems as they provide high-reliability, high-power and high-frequency characteristics.
