This article will explore the common parameters of capacitors, the different types available, popular models, and their applications in electronic circuits. II. Basic Capacitor Parameters A. Capacitance Capacitance is the primary parameter of a capacitor, defined as the ability of a capacitor to store charge per unit voltage. It is measured in Farads (F), with common subunits including microfarads (µF) and picofarads (pF). The capacitance value is influenced by several factors, including the surface area of the plates, the distance between them, and the dielectric material used. Larger surface areas and smaller distances generally result in higher capacitance. B. Voltage Rating The voltage rating of a capacitor indicates the maximum voltage that can be applied across its terminals without risking breakdown or failure. It is crucial to select a capacitor with a voltage rating higher than the maximum voltage it will encounter in a circuit. Capacitors can have different voltage ratings for direct current (DC) and alternating current (AC), with AC ratings typically being lower due to the additional stress caused by the changing voltage.
