Tantalum - Polymer CapacitorsTantalum-polymer capacitors are a type of electrolytic capacitor that utilizes an organic polymer as an electrolyte. It is an automatic type construction capacitor, reference of which is IEC 60384-14. This type of capacitors comes in many different shapes, sizes and capacities. The T541X687M004CT8605 is a type of Tantalum-polymer capacitor, typically used for various electronic applications.Tantalum-polymer capacitors are widely used in a variety of industrial, communication, aerospace, medical, military and consumer products. Its great advantage is its small size and high capacitance. The T541X687M004CT8605 in particular, is a one of the most widely used Tantalum-polymer capacitors. T541X687M004CT8605 is a solid tantalum polymer capacitor that offers high volumetric efficiency and high CV product, making it an ideal choice for applications requiring small size and high capacitance. It has a rating of 6.3V-DC and an operating temperature range of -55°C to +105°. It offers a capacitance range of 47µF to 470µF with tolerances of ±20%.Working PrincipleThe main components of a Tantalum-polymer capacitor are tantalum powder, synthetic organic polymer, aluminum metal and other components depending on the specific type of capacitor. The construction of the T541X687M004CT8605 is a wet-slug type. It has two thick electrode layers, with a small gap in between them. The two layers are then coated with a layer of organic polymer. The organic polymer gets wet with the electrolyte, making it electrically conductive. The tantalum powder is used as the anode, and the other components form the cathode. The anode is then connected to the positive voltage terminal and the cathode is connected to the negative voltage terminal. When a voltage is applied to the capacitors, an electric field is created which causes an electrostatic charge to build up on the two electrodes, thus, creating a capacitor. This electrostatic charge is stored in the capacitor, which can then be used as a source of energy. The capacitance of the capacitor depends on the properties of the materials used to construct it. Because the electrodes of the T541X687M004CT8605 are made up of solid tantalum powder, it can handle higher current densities than conventional aluminum electrolytic capacitors, making it ideal for high frequency circuits. The polymer used also allows for greater flexibility in terms of operating temperatures and stability.Application FieldsT541X687M004CT8605 is mainly used in space-constrained applications or in applications where low-ESR or high capacitance is required. One of the most common applications is in the power supplies for computers, laptops, and mobile phones. It is also often used in DC-DC and AC-DC converters, such as those used for motor control applications, battery operated equipment, and other power electronic applications. The optimal application of the T541X687M004CT8605 depends mainly on the operating temperature and voltage. They are typically used in temperatures from -55°C to +105°, and circuits with voltages of up to 6.3V-DC.ConclusionThe T541X687M004CT8605 is a type of Tantalum-polymer capacitor that provides high volumetric efficiency and consistently reliable performance. It is a compact, high capacitance capacitor that is ideal for space-constrained applications or applications requiring high capacitance and low ESR. It is most commonly used in power supplies and DC-DC/AC-DC converters, and can operate at voltages of up to 6.3V-DC and temperatures of -55°C to +105°C. It is a reliable and efficient type of capacitor for many electronic applications.
