Learn about the different types of capacitors and why you would use different compositions. Leakage is modeled as a relatively large-value resistor in parallel with the ideal capacitor in the lumped model.

The capacitor is a reactive component used in analog electronic filters due to the function of the capacitor’s impedance frequency. Depending on the frequency of the capacitor that affects the signal. This property is therefore widely used in the design of filters.
Switched-capacitor filters are clocked, sampled-data sys-tems; the input signal is sampled at a high rate and is pro-cessed on a discrete-time, rather than continuous, basis. This is a fundamental difference between switched-capacitor fil-ters and conventional active and passive filters, which are also referred to as “continuous time” filters.
The line filter capacitor is applicable in several industrial loads as well as appliances in order to defend the appliance from the noise of line voltage noise and to defend other devices on a similar line from the generated noise within the circuit.
