Film capacitors, or polypropylene capacitors, are a type of capacitor primarily consisting of a thin film of plastic as a dielectric, encased in a copper-plated metal case. They are a type of electrical component that store and release electrical energy, and are capable of handling both large and small amounts of current. One of the most common uses of these capacitors is in analog audio and video applications, where they act as signal filters and sound equalizers.

The 154PSB202K4H is a specific type of film capacitor that is widely used in a variety of applications. It consists of a rolled polypropylene film dielectric for increased insulation, and a copper-plated metal case for strength and electrical shielding. The film is heat-sealed between two copper foil electrodes for superior electrical conduction and low-capacitance loss. The 154PSB202K4H is rated for a voltage of 250V DC at -55°C to +105°C, and its capacitance ranges from 0.04 to 0.10µF. It has a good linearity performance, and a very low dielectric loss and high frequency response.

The 154PSB202K4H is suitable for applications that require high insulation resistance, such as Class X2 and Class Y2 capacitors. It is commonly used in switch mode power supplies, inverters, LED lighting, UPS systems, and industrial control systems. It is also used in many audio and video applications, such as line-matching and filtering circuits, power amplifiers, digital audio amplifiers, preamplifiers, and signal processors. The low dissipation factor of the 154PSB202K4H makes it well-suited for use as a compensation capacitor for the compensation and smoothing of output voltages.

The 154PSB202K4H’s working principle is fairly straightforward. When an electronic current is applied to the capacitor, an electric field is created inside the dielectric material. This electric field redistributes the charge carriers and leads to a static electric charge. This charge causes a current to flow through the electrodes, and results in a voltage between the thereto.

The 154PSB202K4H is one of the most versatile film capacitors, capable of providing excellent performance in a variety of applications. Its heat-sealed electrodes and resistant polypropylene dielectric ensure excellent erosion resistance and very low losses, making it suitable for highly demanding applications. Its compact size and light weight make it easy to integrate into any system, and its low-capacitance loss makes it well-suited for use in sensitive applications such as audio and video processing.
