　　Application of Self Recovery Fuse in RS485 Communication Port Lightning Protection

　　RS485, as one of the most commonly used serial differential communication methods in the industry, adopts a balanced transmission and differential reception method, which has the ability to suppress common mode interference. Due to its long communication distance (over 1200m), high transmission rate (10Mbps), high signal-to-noise ratio, convenient control, low cost, and the ability to achieve multiple nodes on a single bus, as well as the variety of transceivers that can be used, RS485 has the advantages of being able to suppress common mode interference, It has been increasingly recognized by users.

　　However, with the increase in usage frequency, the problems encountered are also increasing day by day. Due to the fact that RS485 communication transmission lines are usually exposed outdoors, lightning and electrostatic interference have become common problems in practical engineering of RS485 communication buses in daily life. The working voltage of RS485 transceivers is low, only 5V, and the withstand voltage of the components themselves is also low, usually only -7V to+12V. Therefore, overvoltage caused by lightning and other factors can instantly damage RS485 transceivers, causing serious damage to the communication system; In addition, static electromagnetic interference also seriously affects the data transmission quality of the communication bus.

　　The Application of Self Recovery Fuses on Tablets

　　Tablets are now digital products for personal applications, capable of completing most of the functions of desktop computers, making them widely used. Tablets are mainly composed of a built-in power supply (lithium-ion battery), a main control board, and an LCD display part. External interfaces include USB, SD card, headphone interface, etc.

sony bravia tv fuse location.Discussion on the Testing Method of Chip Fuses

　　　　We know that there are many series of fuses in the electronic component market, including patch fuses. This series of fuses is commonly used in factories, with few being used by individual users. But what should we pay attention to when testing patch fuses? Today, editor Dai Liang, let's take a look together. Firstly,　　The detection method for patch fuses is recommended to be based on the following aspects: normal current, fusing current, open circuit voltage, short circuit current, impulse current, and ambient temperature.　　1. Normal current: Firstly, we must know the normal current flowing through the fuse in the circuit used. Usually, we need to pre-set a derating amount and choose according to the following principle: the normal current must be less than the product of the rated current and the derating coefficient.　　2. Fusing current: According to UL specifications, the fuse should quickly fuse at twice the rated current. But in most cases, to ensure reliable fusing, we recomm

Delay fuse.smd fuse code

　　　　It is demonstrated that the circuit remains intact when there is a non fault pulse current and can provide protection against long-term overload.　　Delay fuses are used in some circuits where the current at the moment of switching is several times greater than the normal working current. Although this current peak is high, it appears for a short period of time, and we call it pulse current. Ordinary fuses cannot withstand this current, and delay fuses are needed in such circuits. If larger fuses are used, they will not be protected when the circuit is overloaded.　　The melt of the delay fuse is specially processed and has the function of absorbing energy. Adjusting the amount of energy absorption can enable it to withstand both impact current and provide protection against overload. The standards for delay fuses have regulations on delay characteristics. If the specified characteristics cannot meet your requirements, you can contact the delay fuse manufacturer for a solution.

Recoverable fuse low resistance 0603 series parameters and application.supercheap auto blade fuse holder

　　　　There are two resistance specifications for the recoverable fuse ASMD0603 series, one is the conventional resistance series, and the other is the low resistance series. The low resistance ASMD0603SL series provides micro surface mount resettable overcurrent protection, making this world's smallest PTC suitable for ultra portable applications where space is very valuable and device current is low. (ASMD0603 series recoverable fuse)　　The recoverable fuses in the ASMD0603SL series include models ASMD0603SL035, ASMD0603SL050, ASMD0603SL100, ASMD0603SL125, ASMD0603SL150, ASMD0603SL175, and ASMD0603SL200, with a maximum current of 50A and a holding current range of 0.35mA to 2.0A. The maximum working voltage is 6V, and the working temperature range is -40 ℃~85 ℃.　　The main features of the recoverable fuse ASMD0603SL series include: compliance with RoHS standards, halogen-free, and UL certification. This series of fuses has a fast fusing speed, and the 0603 package is small in size. It is

Analysis of the Prospects of the LED Industry, with the Fuse Industry Following a Growth Trend.resettable fuse vs fuse

　　　　With the further increase in global LED market demand, the fuse industry may have a certain impact on factory production. In the future, the development of China's LED industry will face enormous opportunities, both in terms of industry and sales, which will bring a qualitative leap to the LED industry in the market. At the same time, there is further improvement in promoting the development of the fuse industry.　　If the LED industry wants to achieve a healthier future, it is necessary to carry out free market reforms, reduce administrative intervention in industrial development, and more often focus on promoting the process of industrial standardization. Only when there is chaos in the industry, can administrative measures be used to gently correct the development path.　　The reason why the domestic LED industry is showing "photovoltaic concerns" is not due to the industry's own traps. The arrival of a wave of bankruptcy has brought a very urgent feeling to the development of the L

What is the appropriate purchase price for self restoring fuses?smd fuse size chart

　　　　We know that self restoring fuses are made of special materials, which have the advantages of being able to be used multiple times and automatically recovering after overload actions. Compared to ordinary disposable fuses, self restoring fuses are more commonly used in certain products and do not require frequent replacement. Some people may have some doubts, but what is the appropriate purchase price for self restoring fuses?　　What is the price for purchasing a fuse?　　Here, the editor tells everyone that there are both high and low prices for self recovery fuses. According to my investigation, there are currently 0.1-2 yuan range available on the market, and the prices vary from manufacturer to platform. Some manufacturers require lower prices for fuses, but it is difficult to find them. Sometimes, the fuse model you need is less used by others, and the manufacturer produces less, resulting in higher prices. Many manufacturers of electronic products, machinery, and other products
