Digital products generally refer to MP3, U disk, smart phone, digital camera / video camera / scanner and other machines that can be operated by digital and coding and can be connected with computers. For digital cameras, in addition to the lens and photoreceptor, the image processor is also very important. Photosensitive element is the core and the most critical technology of digital camera. There are two kinds of core imaging components of digital cameras: one is the widely used CCD (charge coupled) element; The other is a CMOS (complementary metal oxide conductor) device. Each pixel in a conventional CCD is composed of a diode, a control signal path and a power transmission path. Super CCD uses honeycomb octagonal diodes. The original control signal path is canceled. Only one direction of power transmission path is required, and the photodiode has more space. With the continuous progress of semiconductor technology, many new and fashionable portable electronic products are presented to the world. These portable products put forward higher requirements for electronic components, requiring low power consumption, high reliability and miniaturization. How to select electronic components used in high-quality digital products, such as chip capacitors, high-voltage chip capacitors, chip resistors, chip inductors, tantalum capacitors, precision resistors, electrolytic capacitors, zener diodes, triodes, MOS tubes and other electronic components. It plays an important and decisive role in improving the performance parameters of digital products.
