Capacitors
Capacitors play a vital role in electronic circuits. Reasonable selection and use are the keys to ensuring circuit performance. 1. Capacitors Overview A capacitor is a passive electronic component consisting of two conductors (plates) close to each other and a non-conductive insulating medium (dielectric) in the middle, used to store charge and electrical energy. Its core function is to achieve temporary storage and release of energy through the charging and discharging process. The calculation formula of capacitance (unit: Farad, F) is: C=εS/4πkd Where ε is the dielectric constant, S is the plate area, and d is the plate spacing. 2. What are the Core parameters of Capacitors? Capacitance: There is a tolerance between the nominal value and the actual value, and the accuracy is usually 5%~25%. Rated voltage: The maximum voltage limit for the normal operation of the capacitor. Dissipation factor: Reflects the energy loss of the dielectric material and the equivalent series resistance (ESR). Temperature coefficient: The effect of temperature change on capacitance, expressed in ppm (parts per million). Leakage current: Determined by dielectric insulation performance, affecting long-term stability. 3. What are the Types of Capacitors? 1) Differentiation by polarity: Non-polar capacitors: Such as ceramic capacitors and film capacitors,…
