Film Capacitors

A film capacitor is one of the essential components of electronic devices and equipment. It is made of two thin layers of polymer film (usually polypropylene) separated by an electrically insulating dielectric medium such as air. The layers are connected to a plate or substrate to form an electrical component. Film capacitors offer many advantages such as small size, high-temperature stability, high capacitance per unit volume, low ESR, and long lifetime.

To take one specific example, the 474PPA700K is a film capacitor designed for use in a variety of markets and applications. It has two layers of metallized polyethylene terephthalate (PET) film and is housed in a PCB mountable, UL 94V-0 rated thermoset plastic case with epoxy resin sealant. It can be used in a range of DC and low-frequency AC applications.

Application field and working principle

The 474PPA700K is suitable for a wide range of applications including decoupling, bypassing, signal coupling, oscillator circuits, smoothing, clamping, and power line filtering. It is designed to operate at temperatures ranging from -55°C to +125°C for both commercial and industrial applications. It can handle a working voltage of up to 85V DC.

The 474PPA700K works on the principle of capacitance. In a capacitor, when alternating current passes through it, the capacitor will decrease or increase its voltage, creating an alternating current (AC). The higher the capacitance, the more charge it can store, and the longer it can last, making it suitable for long-term storage and smoothing of voltage. The 474PPA700K has a capacitance of 0.1μF with a maximum capacitance tolerance of ± 10%.

The 474PPA700K has a high insulation resistance between the two layers of PET film, minimizing leakage of electrical current. The metallized PET film provides optimal performance in terms of size, cost, and stability. It also has a high dielectric strength, making it ideal for high-voltage applications. The construction of the 474PPA700K also ensures excellent electrical and mechanical performance.
