Film Capacitors

Film capacitors are types of capacitors with high performance where the dielectric material is made of thin plastic film. Specifically, B32526R1336K000 is a metalized film capacitor of high stability. They are mainly used for power electronics, such as power supplies or inverters, frequency conversion and lighting. This component is characterized by a long-term stability of the electrical characteristics and low dissipation factor.

Application Field

B32526R1336K000 can be applied in AC and DC circuits, both in signal and power applications, such as in power supplies, frequency changers, motor drives, LED lighting and more. It offers protection against high inrush current, as well as noise filtering and isolation from high-frequency signals. As the insulating layer of B32526R1336K000 is made from polypropylene film, it is ideal for environments with a wide temperature range from –40°C to +125°C. Also, the self-healing property of its dielectric ensures that it can continue to operate even if a slight breakdown occurs. The dense structure of the capacitor enables it to withstand ultra-low impedance and high frequency noise.

Working Principle

The working principle of a B32526R1336K000 film capacitor is similar to that of a regular capacitor. It utilizes two conductive surfaces to store energy by accumulating an electric charge. The electric field between the two surfaces creates a force which is responsible for building up a charge in the capacitor’s plates. An electrical current flows through the capacitor when the voltage is applied to it. The current flows in and out of the capacitor, depending on the sign of the voltage. Depending on the application, the capacitor utilizes either a DC or an AC current.

As a result, a film capacitor can act as a low-pass filter, rejecting high-frequency noises while preserving the desired frequencies. This provides protection against transient overloads and ensures that the discharge current is under control. In addition, the capacitor also has an excellent ripple current capacity which ensures that the power output is stable.

When it comes to the use of film capacitors, it is important to note that they are temperature dependent and tend to drift out of their desired capacitance range when exposed to high temperatures. To avoid this issue, it is necessary to incorporate a temperature compensation feature in the design of the circuit.
