Ten Elements of Fuse Selection

　　　　Fuse selection is a step that circuit design engineers must be cautious about. If the protective components of the circuit are not selected properly, the entire process of powering on the circuit will be affected, and the normal use of the product will also be affected. So today, let's learn about the ten key points of fuse selection:　　Key points for fuse selection: rated current;　　Key points for fuse selection 2: rated voltage;　　Key points for fuse selection: environmental temperature;　　Key points for fuse selection: voltage drop/cold resistance;　　Key points for fuse selection: fusing characteristics: overload capacity, time/current characteristics;　　Key point six for fuse selection: breaking capacity;　　Key point seven for fuse selection: melting heat value;　　Key points for fuse selection: durability (service life);　　Key points for fuse selection nine: structural features: appearance/size, installation form;　　Key points for fuse selection: safety certification.

Chip fuse specifications | price

　　　　SMD fuse specifications | price - SMD fuses can be divided into SMD disposable fuses and SMD self recovery fuses. Among them, the specifications of patch disposable fuses include series 060312062410 fuses, and the specifications and dimensions of patch self recovery fuses include series 0603, 0805, 1206, 1210, 1812, 2920, etc.　　The price of SMD fuses varies depending on the type. The latest quotation for SMD fuses in the market is around a few cents, with wholesale prices. Good quality products can be sold for around one yuan. There are differences in prices between suppliers and traders, so when searching for products in bulk, it is more advantageous to find manufacturers and suppliers.　　Chip fuse specification | price - The fuse must be a fusible metal wire in order to fuse in a timely manner and provide protection when the current is high. The fuse material is mainly made of low melting point alloys such as aluminum antimony alloy.　　There are four basic forms of patch fuses: slo

Application of PPTC Thermistor in Batteries

　　　　Compared with NiMH or NICd batteries, lithium-ion batteries have a higher current density and are widely used in various portable devices.　　Lithium ion batteries are usually very sensitive to overcharging. When the voltage at both ends of the battery is too high during charging, it will increase battery leakage　　The danger of smoking, burning, and bursting (which is often quite severe). Overcharging may be caused by uncontrolled charging, electrode errors, or　　Caused by using an incorrect charger. When the charging and discharging current of lithium-ion batteries is too high or there is an external short circuit, internal heating may damage the battery or burn other components, seriously shortening the battery's cycle life.　　The task of protecting the circuit is to monitor the parameters of the battery's charging and discharging status in response to various possible faults, in order to ensure battery life and efficiency, and to prevent damage to the battery and external devices su

0.3A self recovery fuse parameters.ceramic fuse sizes

　　　　Fuses can be divided into recoverable and disposable fuses. Recoverable fuses are commonly referred to as self restoring fuses. The biggest functional feature of these fuses is that after the circuit fault is eliminated, the fuse can be restored for recycling; The disposable fuse is what we refer to as a disposable fuse. It is disposable and cannot be reused and must be replaced. Its biggest functional feature is its high segmented ability, which can be divided into fast break and slow break fuses; Fast or slow break refers to the reaction speed of the fuse to the fault current. Today we will learn about the relevant parameters of a 0.3A self recovery fuse.　　There are two types of 0.3A self recovery fuses, domestic and imported. Currently, there are several models of domestic 0.3A self recovery fuses available in stock in Shenzhen, including A6-030, A16-030, A30-030, A60-300, A72-300, ASMD1812-030, ASMD1206-030, ASMD2016-030, and more. Among them, A6-030, A16-030, A30-030, A60-300,

The Protection Application of Self Recovery Fuses in Sweepers.mini cooper fuse box symbols meaning

　　　　With the rapid development of modern technology, a large number of products can only be integrated into our daily lives, and the broom is one of them. As a smart home product, floor sweepers are not uncommon in first tier cities in China. The working principle of a floor sweeper is not too difficult to understand, mainly relying on the drive of internal small motors to provide power. Due to unstable voltage or jamming during operation, the motor may encounter problems such as rotor blockage, overload, or even burning out. So the internal motor must be designed with corresponding protection circuits to ensure its reliability and stability of operation.　　There are many types of protection methods for small motors inside the sweeping machine. Previously, bimetallic temperature controllers were commonly used. When the motor was working, if the coil temperature increased, the circuit would be disconnected, and after the temperature decreased, it would be connected again. However, this m
