Most SMD fuses look like standard SMD devices, using single or multi-layer ceramic substrates. Some previous designs used epoxy glass fiber substrates similar to printed circuit boards. Its structure includes: a shell, a lower cover, quartz sand, a fuse, and two terminal blocks. The shell is a ceramic box like structure without a bottom surface, and the two terminal blocks are connected together through a suspended fuse set inside the shell, which is clamped on the edge of the shell. The basic fuse in the middle is a high conductivity material, such as copper, gold or copper tin, silver palladium alloy. Depending on the type of substrate, the fuse can use laser fine tuned thick film deposits or chemically etched metal layers to achieve the desired performance parameters, and adhesive gold wires can also be used. Due to the determined shape and thickness, when subjected to overvoltage and the current reaches a certain level, the fuse will fuse within a certain period of time. To a
1. What is a fuse clip? Fuse clips refer to clips for installing fuses, which can be divided into two types: current fuse clips and automotive fuse clips. The clips for car fuses are usually installed on the panel PCB board and can be directly inserted into the circuit board for welding. They are located among various components of the car. Due to the small overall volume of the car and the complex internal mechanical structure, we place the fuse in the clip, which can facilitate maintenance personnel to immediately find and quickly troubleshoot the fault situation. At the same time, the role of clips is mainly reflected in safety aspects. 2. Why use a fuse clip? For those familiar with industrial production, friends are familiar with the function of fuse clips because fuses are very small electronic devices, and most people tend to overlook them during use. Especially in large equipment, the installation and maintenance of safety components such as fuses are relatively difficul
Three terminal fuses are chip based surface mount products, commonly used as secondary protection for lithium-ion battery packs to act promptly when damaged by excessive current and overcharged voltage, effectively protecting lithium-ion batteries from fires caused by overcurrent and overcharging. The three terminal fuse adopts an extremely thin and compact surface mount packaging (SMD), and is compatible with up to 14 battery cells. At the same time, to facilitate the solution of different product design needs of users, Linda can provide a variety of three terminal fuse product solutions to meet the requirements of different currents and packaging sizes. Three terminal fuse applications include: Wireless vacuum cleaners and sweeping robots, rechargeable electric tools, Garden tool, laptops, electric bicycles, electric motorcycles, uninterruptible power supplies, portable energy storage and other products. Internal structure and working principle of three terminal fuse: Consist
At present, there are various types of charging cables on the market. With the development of technology, magnetic suction charging cables have gradually entered people's lives as a new type of charging method. Magnetic charging cables, also known as magnetic charging wires, magnetic cables, magnetic data cables, etc., are widely used in fields such as intelligent wearable, smart home, 3c digital, medical equipment, in car navigation detection, industrial equipment, etc. to achieve signal transmission and charging functions. Compared to traditional charging methods, magnetic suction charging wires have unique advantages in use: the principle of magnetic suction wires is mainly to transmit current through spring needle pogo pins. As a variable structure connecting component, pogo pins have strong adaptability. They use magnetic adsorption to automatically adsorb and connect ports without frequent plugging and unplugging, support high current and fast charging, and achieve high-frequ
In recent years, with the rapid progress of science and technology, the market of intelligent wearable devices has become more and more popular. At present, intelligent wearable devices such as smart bracelets, smart watches, Smartglasses, health wear, ear wear devices and somatosensory control are increasingly popular in the market. Intelligent wearable devices can bring convenience and guarantee to people's lives through software support, data interaction, cloud interaction and other ways. Intelligent wearable devices require direct contact with the user's body, so the safety and stability of the product are crucial. Below, we will provide a detailed introduction to the potential safety hazards and solutions of intelligent wearable devices. The safety hazards of intelligent wearable devices include the following three points: 1. PMIC (Integrated Power Management Circuit) failure The product designer will add some overcurrent protection components to the charging port to cope wit
USB Type-C (hereinafter referred to as Type-C) is the latest standard for USB connectors. There is no distinction between positive and negative sides, and the data transmission speed can reach up to 10Gbits/second (Gbps), supporting "USB Power Delivery (PD)" power supply. However, as the charging current increases, the likelihood of accidents such as abnormal heating and burning of connectors also increases. So in order to prevent such accidents from happening, it is necessary to equip the TYPE-C with an overcurrent protection element - PPTC thermistor, also known as the PPTC self recovery fuse. PPTC is a component that blends carbon into a polymer resin and sandwiches it between metal foils. In normal working conditions, the resistance of PPTC components is much lower than other components in the circuit. Under overcurrent, the resistance of the components increases (acts), thereby reducing the current in the circuit to a value that other circuit components can safely carry. This
