Film Capacitors

Capacitors are found in nearly all electronic circuits and offered in a wide variety of types and sizes. Film capacitors, in particular, offer several advantages over other types of capacitors when it comes to maximizing performance. They are designed to meet a variety of application needs, such as energy storage, power conversion, and signal filtering. Film capacitors provide reliable performance in extreme temperature and harsh environments, while also being relatively low cost.

947D271K122CDRSN is one of these film capacitors, featuring a capacitance of 271pF, a rated voltage of 50V, and a capacitance mounted between terminals that measure 12.7mm x 17.3mm. This capacitor is a low-cost, high-reliability device suited for consumer applications.

Application Field

947D271K122CDRSN film capacitors are highly suitable for consumer devices like phones, tablets, mp3 players and other audio equipment. This type of capacitor is also used for any other high frequency circuit, including DC-DC converters, power management, and audio and video applications.

The 947D271K122CDRSN film capacitors are often used in voltage regulating circuits due to their small size and low cost. They are also used for harmonic filtering of low voltage power supplies, and in any other application requiring a wide range of capacitance values.

In addition, these film capacitors are also used in the production of oscillators, waveform filtering, and time-delay circuits. These capabilities are important for any device that requires a precise frequency. In addition, the 947D271K122CDRSN capacitors are also used in feedback or damping circuits for fine-tuning the performance of a system.

Working Principle

Film capacitors provide reliable performance in electronic circuits due to their construction and design. An ideal capacitor can store and release energy in the form of an electric charge. Film capacitors contain one or more pieces of thin polymer resin film as their dielectric, or electrical insulating material. The plates of the capacitor are each layered with a conducting metal such as aluminum, which forms the electrical connection between the capacitor plates.

When applying a voltage across the capacitor plates, the electrical field created across the dielectric film attracts charges and creates a potential difference. The electrical field stores energy, and it is this stored energy that is used when the voltage applied across the plates is removed.

Film capacitors also feature some distinct advantages over other types of capacitors. Due to their thin layer of dielectric, they can hold much more charge than ceramic or electrolytic capacitors. Additionally, the thinness of the dielectric enables the construction of much higher capacitance in a small area then compared to other types of capacitors. Film capacitors also have very low levels of electrical and magnetic field interference and can operate over a wide range of temperatures and frequencies.

The 947D271K122CDRSN film capacitor generally has a rated temperature range of -30°C to 85°C. The rated voltage and capacitance are typically guaranteed at +20°C. It is important to consider the ambient temperature of the environment where the capacitor will be installed before selecting a capacitor.

For most applications, film capacitors have proven to be reliable and cost-effective solutions. They can be used in a variety of applications, from signal filtering to energy storage. The 947D271K122CDRSN film capacitor is just one example of how to maximize performance and reliability while also keeping costs low.
