Capacitance refers to the ability to hold a charge. It is a medium for realizing the storage and release of static charges, with the characteristic of permanent charge storage. Capacitor components are widely used in power supply filtering, signal filtering, signal coupling, resonance, filtering, compensation, charging and discharging, energy storage, and power separation in circuits. According ...
Photometric Testing is an important step in ensuring the intensity and distribution uniformity of street lights. The luminance measurement is a commonly used testing instrument that can measure the photometric distribution of street lights and provide accurate data analysis. This article will discuss the methods and steps of using a luminance measurement for Photometric Testing, as well as some c...
This article briefly explores the causes and consequences of ESD and EMI in mobile audio systems. It then discusses the use of ESD suppressors and EMI filters to mitigate these threats. Finally, it compares three current solutions. Modern materials and technologies have led to the frequent occurrence of electrostatic discharge (ESD) and electromagnetic interference (EMI), which pose significant ri...
With the development of technology and increasing environmental awareness, people are paying more attention to the environmental friendliness of products. RoHS (Restriction of Hazardous Substances) is a regulation issued by the European Union that aims to restrict the use of hazardous substances in electronics and electronic equipment to protect human health and the environment. RoHS testing refer...
We know that the quantification of color and light is in an abstract sense, so the differences in color and other physical differences are distinct. For example, when we use a measuring stick to measure the length of an object, people often arbitrarily divide it into uniform small segments. Even small lengths that cannot be distinguished by the human eye can be judged by measuring tools. But when ...
Electrical Safety Withstand Voltage Test Standards： Electrical Safety Withstand Voltage Test is an important indicator for measuring the insulation performance of electrical equipment, and its effective measuring standards are: For general test equipment, leakage current values between the spark wire and the shell can be measured, the basic standard requires two times the working voltage plus 10...
What is Hot Wire Test? Hot wire test is a common experiment methodology that is used to study the combustibility and thermal stability of materials. By placing the material above the hot wire and heating the hot wire, it is possible to evaluate the fire hazard and fire protection performance of the material by observing whether the material is ignited and the burning behavior after ignition. Prin...
The ozone aging test chamber is mainly used to study the action law of rubber, simulate and strengthen the ozone conditions in the atmosphere, and achieve rapid identification and evaluation of rubber’s ozone aging resistance performance and the protective effect of ozone agents; Furthermore, effective anti-aging measures are taken to improve the service life of rubber products. Usage of ozo...
Does SO2 cause corrosion? The answer is yes. Sulfur dioxide (SO2) is a common and relatively simple sulfur oxide and one of the major air pollutants. It has strong corrosivity and reacts with homogeneous materials to form salt substances to corrode the surface of the material and disintegrate the material into particles, eventually causing the material to age, fail and damage, and also affecting t...
