Tantalum capacitors are devices specifically designed to store electrical energy in an electric field, similar to a battery or other electrical components. These capacitors are used in many applications for their high capacitance and low leakage current. They are also available in a variety of configurations to meet various engineering requirements.T491A335K004AT is a type of tantalum capacitor widely used in electronics and telecommunications. It is a surface-mount device with an electrically conductive polymer cathode construction. This type of capacitor is capable of storing a wide range of capacitance from 15μF to 2.2mF, depending on the size and polarity of the capacitor. It is designed to operate over a wide temperature range of up to 125°C, with an operation temperature range of -55°C to 125°C. This capacitor is also capable of quick and reliable discharge, making it ideal for use in high-speed switching applications.The T491A335K004AT can also be used for General-Purpose Applications, such as decoupling or bypass capacitors, AC line filters, and DC snubbers. In these applications, the capacitor is able to store energy and act as a buffer between source and load. This function is essential for reducing EMI radiation and providing a stable power supply current for the AC line filters and DC snubbers.The construction of the T491A335K004AT is based on an anode consisting of a tightly rolled cylindrical template, with a small plastic tube at one end. The anode is connected to a metal conductive cathode strip that is embedded into the plastic tube. The cathode strip contains a polymer material (used as a dielectric) that serves as the capacitor’s dielectric medium. The metal conductive cathode strip is then encased in a highly durable, wear-resistant coating designed to protect it from environmental and mechanical damage. The working principle of T491A335K004AT is based on the storage of electrical energy as an electrical field between two oppositely charged surfaces. When a voltage is applied across the capacitor, a positive and negative charge forms across each plate. This charge is capable of being stored in the battery for indefinite periods of time until needed. The T491A335K004AT also utilizes a self-healing process to deal with over-voltage issues. This process involves the gradual reconnection of the two plates in order to sustain voltage limits and return the capacitor to its original state. This repair process is much quicker and more effective than repairing the capacitor with a manual soldering iron.The T491A335K004AT is a reliable and efficient way to store energy in a compact form. Its wide temperature range and self-healing properties make it ideal for a variety of applications, especially those that require high performance and efficient operation.
