Working Principle of RL81C221MDN1KX Aluminum-Polymer Capacitor

The RL81C221MDN1KX aluminum-polymer capacitor is a polarized (or bi-polarized) device, as it is required to connect the positive lead to the positive terminal and the negative lead to the negative terminal. It is also a non-polarized device, as it is not affected by incorrect polarity. This capacitor consists of two electrodes, an aluminum cathode metal layer and a polymer dielectric layer. The electrostatic field created between the two electrodes determines the capacitance of the device.

When an AC or DC voltage is applied across the device, an electric field will then be generated between the two electrodes. This electric field then causes the rate of charge storage to increase or decrease depending on the polarity and magnitude of the applied voltage. This results in a capacitance change that is proportional to the applied voltage. This change in capacitance is referred to as capacitance variation. This capacitance variation allows the device to act as a variable capacitor, and this is how the RL81C221MDN1KX aluminum-polymer capacitor works.

The RL81C221MDN1KX aluminum-polymer capacitor is a reliable, low-cost solution for applications requiring high capacitance, low impedance, and good thermal reliability. With its wide range of features, the RL81C221MDN1KX capacitor enables design engineers to produce highly efficient electronic devices.
