  • Introduction

    A capacitor, one of the most essential components in electronics, is a passive bipolar component that stores electrical energy in an electric field. Its storage capacity, known as capacitance, is expressed in units of Farad (F). It consists of two conducting plates separated by a dielectric, an insulating substance. When a voltage is applied across the plates, the positive charge collects on one plate and the negative charge on the other. The collected charge remains in the capacitor until it is released through a conductor.
  • Types

    Depending on the dielectric used, there are different types of capacitors such as ceramic, aluminum electrolytic, tantalum, film and supercapacitors. Ceramic capacitors are often used for their stable properties and high dielectric strength. Electrolytic capacitors, which are reverse polarized, have a large capacity and are often used in power supply filters. Tantalum capacitors are valued for their high performance and long life.
  • Application

    Capacitors are used in numerous electronic applications. From power filters, ignition circuits in cars, to coupling and decoupling in various types of electronic circuits. In the digital domain, capacitors are used to store data in dynamic RAMs. In the analog world, they are used in filters to select or remove specific frequency bands. Capacitors can also be used to store energy for later use, such as in flash units for cameras.
  • Product range

    There is a wide range of capacitors available on the market, varying in capacity, working voltage, tolerance and other specifications. Choosing the right type for a specific application is critical to circuit performance. The choice depends on several factors, including required capacitance, operating voltage, ambient temperature, dimensions and cost.
  • Tech fact

    Electrolytic capacitors are one of the most commonly used types because of their high capacitance per volume. They are polarized, which means they have a positive and a negative terminal and must be oriented correctly in a circuit. They have an electrolyte as one of their conducting plates and a thin oxide layer as a dielectric. This oxide layer is formed through a process called formation, in which a voltage is applied to the capacitor in an electrolytic solution. The thickness of this oxide layer is proportional to the formation voltage and determines the rated voltage of the capacitor. It is important to note that reverse voltage can destroy this oxide layer, leading to a short circuit and possible failure of the capacitor.
