Capacitors come in many forms, each designed for specific applications and operating conditions. Let’s take a closer look at the most common types of capacitors: Ceramic capacitors are small and stable, often used in high-frequency applications such as shortwave radio and aviation air-to-ground communications.
You can identify a capacitor by examining its physical characteristics. Capacitors typically have markings that indicate their capacitance value (often in microfarads, µF), voltage rating, and sometimes the type (e.g., ceramic, electrolytic). The physical size and shape (cylindrical, disc, rectangular) can also give clues about its type.
Before going to each of them, let us understand the basic uses of a capacitor in a circuit. Capacitors are widely used in electrical and electronic circuits. In electronic circuits, small value capacitors are used, to couple signals between stages of amplifiers. as components of electric filters and tuned circuits.
Capacitors are classified based both on their polarization as well as their structure. Fixed capacitors are types of capacitors in which the capacitance is fixed at a specific value during manufacturing. These devices maintain a constant charge and energy output. These have their capacitance values fixed during manufacturing.
Used for a variety of scenarios, here is an example of the many: Power Supply Systems: this component smoothens voltage fluctuations by storing excess energy and releasing it when required. Signal Processing: capacitors here block the DC component and allow AC signals to pass instead. Thus playing a role in filtering circuits.
The circuit model of a capacitor consists of a series resistive element representing the ohmic resistance of the conducting elements along with the dielectric resistance. This is called the equivalent, or effective, series resistance (ESR). The dielectric effects occur when AC signals are applied to the capacitor.
