Tantalum CapacitorsTantalum capacitors have become a vital component in modern electronic devices since their introduction in 1970. Applications are diverse and range from automotive to medical, telecom and graphics communications technologies and more.The F721A476MRC is a tantalum capacitor manufactured by Kemet. It is a surface mount device with a lead-free and RoHS compliant termination. This capacitor offers high capacitance values in a small form factor and is rated at 10 volts.The F721A476MRC capacitor is an electrolytic capacitor, and has the same structure of any other electrolytic capacitor. It is composed of two plates of metal foil that are separated by a thin dielectric film made from tantalum pentoxide. This forms a two-terminal device that is used to store energy in the form of electrons.When a voltage is applied across the plates, the oxide film acts as a semi-conductive barrier, or dielectric, and prevents the electrical flow from the positive plate to the negative plate; however, it allows electrons to flow from one plate to the other. This electrical property is known as capacitance and is measured in farad. The capacitance of a capacitor is determined by the thickness and the area of the plates, and the dielectric film.In the F721A476MRC, this dielectric film becomes polarized when a voltage is applied to the capacitor, leading to energy being stored in the capacitor. To be specific, a charge of electrical energy equivalent to the applied voltage is stored in the form of electrons. During a charging cycle, the capacitor takes time to fill up with charge; this time is known as the RC time constant and is determined by the product of the resistance of the component in ohms and the capacitance of the component in farad.The F721A476MRC is a polarized capacitor and must be handled with extra care. It has a maximum operating voltage of 10V and is available in capacitance values ranging from 270nF to 4.7µF. The F721A476MRC is suitable for use in stable power supplies, oscillators, timing circuits and high frequency AC power source circuits.In summary, the F721A476MRC is a surface mount tantalum capacitor used in various electronic applications to store electrical energy. It is a polarized capacitor with a maximum operating voltage of 10V. It offers high capacitance values in a small form factor and is easy to use in most circuits. The F721A476MRC is suitable for use in stable power supplies, oscillators, timing circuits and high frequency AC power source circuits.
