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.
As the lumped model suggests, real-world capacitors behave like series-connected LCR circuits. As the frequency of an applied AC voltage increases, the inductive reactance of the ESL increases to a point at which it is equal to the capacitive reactance of the device, and the capacitor behaves as a resistor.
Choosing your capacitor primarily depends on your application and budget constraints. The price of capacitors can vary, from less than a cent to more than $100. Let’s take a look at the capacitor types, where they are used, and when one is more suitable than another. Easily design schematics of any complexity.
An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors.
Although all the different types of capacitors provide capacitance - they are not all equal. Capacitance is not the only critical parameter when selecting a capacitor, and each type of capacitor is used in different applications, so sometimes making the right choice is not an easy task.
This makes the polymer capacitors excellent for power supplies and audio applications. While a polymer capacitor is typically more expensive than other alternatives, it can offer cost savings over ceramic capacitors due to the reduction in capacitance at the voltage in ceramics - requiring fewer polymer capacitors to do the same job.
