MOS transistor has a very high input resistance. However, it is also very sensitive to electrostatic discharge (ESD) due to its high input resistance and very small gate-source capacitance. The MOS transistor can easily become charged when exposed to external electromagnetic fields or static electricity. Moreover, in situations with strong static electricity, it is difficult to discharge the accum...

Introductio Electronics play a crucial role in modern society because of how pervasive technology has become. Every electronic gadget, from cellphones to car systems, is built to function properly and dependably in a diverse array of climatic circumstances. The reliability and performance of electronic equipment under severe temperatures is a major problem for the electronics industry. In this res...
Introduction The use of charge-coupled device (CCD) goniophotometry has greatly advanced the study of light. Thanks to developments in charge-coupled device (CCD) technology, today’s goniophotometers can capture and analyze light distribution with more accuracy, flexibility, and efficiency than ever before. In this article, we’ll look at how recent developments in CCD-based goniophotom...
The special light source hanging in the stalls is also known as the “freshness lamp”. By adjusting the color, brightness, and color temperature of the lighting, it makes the ingredients appear fresher and more glossy. It is often seen in agricultural markets, supermarkets, and other consumer places. The “freshness lamp” has received widespread criticism from the public as i...
LSG-1890BCCD/LSG-1800ACCD goniospectroradiometer is high precision automatic goniophotometric instrument for luminous intensity distribution measurement with facility for rotating the light source. The LSG-1890BCCD/LSG-1800ACCD can do the spatial CCT test and the intensity distribution test. It is for industrial laboratory photometric data measurement of luminaires such as LED luminaires, LED Plan...
Introduction: Despite the widespread belief that electrostatic discharge or ESD guns are exclusively useful for testing electronics, this is not the case. Electrostatic discharge (ESD) guns are useful in many fields and types of testing since they measure a device’s resistance to ESD. Beyond its use in testing electronic components, this article explores the many other areas where ESD guns h...
Introduction Numerous scientific, industrial, and commercial endeavors rely on precise light measurement. High precision spectroradiometer integrating sphere systems have been developed as potent instruments to address the requirement for accurate light characterization. The precise and consistent measurements made possible by these cutting-edge devices are invaluable to scientists, engineers, and...
Protection of Users-Accessibility of Uninsulated Live Parts and Moving Parts-and User Servicing The requirements in 8.2- 8.17 apply only to low voltage parts that are accessible to the user and are isolated from medium voltage circuits. See 8.18 for requirements for medium voltage parts and low voltage parts that are not isolated from medium voltage circuits. For protection of service personnel re...
