Tantalum - Polymer Capacitors are a type of capacitor that utilizes a combination of tantalum and a polymer material to provide high capacity values in a small profile size. The F321A476MBA is a prime example of this, with its small form factor. The F321A476MBA is a surface mount device that has a capacitance of 4,700µF and a rated voltage of 6.3V. It is for use in DC/DC converters, switching regulators, and various other power supply applications.

The F321A476MBA is constructed from Ta/polymer material of low ESR and a voltage polymer that is intended to provide better mechanical performance and reliability. This combination of materials eliminates the need for current limiting resisters and also offers a wide range of capacitance levels as it is not limited to just a couple of values. Due to the high capacitance and low ESR, it is able to support large amounts of inrush current, which is why it is primarily used in DC/DC converters and other power supply applications. Additionally, the F321A476MBA features a high ripple currently rating of 1.5A.

The way in which the F321A476MBA works is by utilizing a pair of plates and sandwiching them with a layer of tantalum and a polymer. This sandwich is then enwrapped and sealed in electrolyte. As current passes through the T/poly material, it holds an electrical charge, allowing for an electrical energy exchange. This energy exchange lets the capacitor store energy in the form of a voltage, which is released whenever needed by the application.

The F321A476MBA operates with a high capacitance of 4,700µF and a wide temperature range of -55°C to 105°C. This makes the F321A476MBA a great choice for circuit board applications that require high capacitance and wide temperature tolerance. Additionally, the F321A476MBA has low ESR and is relatively resistant to vibration and shock, which makes it ideal for applications that require high reliability.

In conclusion, the F321A476MBA is a tantalum - polymer capacitor that provides a high capacitance value and reliability, making it a reliable solution for DC/DC converters and other power supply applications. With its combination of tantalum and polymer materials, it is able to handle high inrush current loads and operate with a wide temperature range. It is a great choice for circuit board applications that require high capacitance and wide temperature tolerance. As a result, the F321A476MBA is a reliable and cost-effective solution for many industrial applications.
