T491X687K006ZTZV13 is a type of tantalum capacitors, characterized by high capacitance, long-standing stability, low internal resistance and high working temperature (up to 125°C). Besides, the service life of such capacitors is long, and loss is low. As a result, T491X687K006ZTZV13 tantalum capacitors have wide application fields and are widely used in many industry fields.

T491X687K006ZTZV13 are generally applied in high-reliability electronic equipments like aerospace, military, medical device and communications products. By specifically operating in electronic circuits, T491X687K006ZTZV13 provides stabilized volumetric capacitance ratio at varying temperatures with high-voltage operation (up to 63VDC). And for its unique advantages like high power density, wide temperature range, long service life and low leakage current, T491X687K006ZTZV13 can also be used in high-temperature, low-voltage, high-frequency and high-quality power supply fields.

T491X687K006ZTZV13 tantalum capacitors are made up of two metal plates, a positive plate and a negative plate, separated by a dielectric material. When current runs through the tantalum capacitor, electric charges accumulate on the positive and negative plates. With the help of Anode Dissolved Metal (ADM) anode technology, the positive plate is coated with tantalum powder. By oxidizing at high temperature, an insulating layer is formed on the plate’s surface, thus creating a dielectric layer. The capacitor’s capacitance is thus established.

In order to maintain its long service life and stability, the anode dissolution rate and water absorption of the capacitor must both be controlled. Moreover, the exposure of the plates to electrolytic solution is to be avoided. Thus, T491X687K006ZTZV13 tantalum capacitors are usually packaged in different types of enclosures with epoxy resin sealant or ultrasonic welding, to ensure that the plates do not come into direct contact with electrolyte medium.

T491X687K006ZTZV13 enjoy exceptional features and have wide application fields. The dielectric layer is formed by surface oxidation and thus the capacitor displays stable characteristics. With its good performance and reliability, T491X687K006ZTZV13 tantalum capacitors are widely used in a variety of electronic equipments.
