Application of film capacitors in mobile phones

The development of science and technology is becoming more and more rapid. At the same time, people are more and more dependent on mobile phones. The performance of mobile phones is stronger, the quality is better, the appearance is better, the lighter and thinner, which is not only higher for mobile phone manufacturers. At the same time, it is even higher for capacitor manufacturers. Although core processors have always been the focus of attention, passive components such as capacitors and resistors, which play a supporting role, also play an important role in miniaturization of propulsion products.

The film capacitor has the characteristics of small size, large capacity, high insulation resistance, etc. It can be used in high frequency and high temperature environments, so it is especially suitable for handheld devices. The film capacitor can meet a wide range of applications from below 3V to thousands of volts. Based on unique design and processing technology, film capacitors are available in a variety of sizes, from ultra-small sizes to large capacitors used to replace tantalum and electrolytic capacitors, and low ESL, high frequency and alignment products, thin films. Capacitors can meet almost all possible application needs.

It is only a film capacitor, and there are requirements for further subdivision according to capacity, use, etc., and thus a large number of capacitors of different packages and capacities are derived. Large-capacity film capacitors can be used for decoupling and smoothing to achieve wire-bonded chip bonding. They can be used for medium and high voltage high frequency buffering. The loss value is low for medium and high voltage decoupling and smoothing, and is also suitable for communication equipment. Continuously improve the composition and properties of materials. The continuous prosperity of the handheld device market will definitely lead to a huge capacitor market, and the film capacitor will continue to exert its advantages of small size and good performance.

Although it is not practical for us to open the mobile phone to see the use of capacitors to select the mobile phone, we can judge by the quality and performance of the mobile phone. Good capacitors must have good performance and longevity. I hope the content of this article will be available to everyone. help.
