F751C157KDC Capacitors

Tantalum capacitors are widely used in electronics applications because of the combination of their relatively low cost, relatively high capacitance-volume ratio, and low equivalent series resistance (ESR). The F751C157KDC is a solid organic polymer type tantalum capacitor that provides high capacity for its size and is characterized by its wide temperature range and extremely low ESR.

The F751C157KDC is polarised, so it has a positive (+) and a negative (-) lead. Each lead has capacitance, and the total capacitance of the device is the sum of these two capacitances. The capacitance is expressed in Farads, and is the principle measure of a capacitor\'s ability to store electrical energy. The F751C157KDC has a capacitance of 15μF.

The F751C157KDC is a surface-mount device, and uses a standard two-terminal lead configuration. The metal alloy casing is hermetically sealed and provides a stable environment for the polarity-sensitive dielectric and electrolyte materials inside. The metal casing also protects the dielectric material from moisture and other contaminants, thus ensuring a long, reliable life.

The internal construction of the F751C157KDC consists of a tantalum pentoxide (Ta2O5) anode, encased in an anodised tantalum metal shell, a negative cathode made of manganese dioxide (MnO2), and a conductive electrolyte. The combination of these materials creates a chemical reaction when there is current flowing through the capacitor, driving electric charge across the plate separation.

When operating, the F751C157KDC acts like a standard capacitor by blocking the flow of direct current (DC) while letting the AC signals pass through. The capacitance is determined by the cross-sectional area of the capacitor plates, and the distance between the plates. This distance is adjustable by the user regardless of the package size and is called the capacitor\'s voltage rating. The F751C157KDC has a rated voltage of 10Vdc, allowing it to be used in a wide range of applications.

The F751C157KDC is suitable for use in many electronic applications including power supplies, medical devices, automotive applications, and communication equipment. It is an excellent choice for low power audio applications where size and cost savings are important.

In summary, the F751C157KDC is a high capacity and low ESR solid organic polymer type tantalum capacitor that is suitable for use in a wide range of applications. Its small footprint, low cost, and wide temperature range make it an ideal choice for many electronics applications.
