With the development of electronic technology and the upgrading of electronic products, the requirements for reliability and safety of power electronic products are increasing day by day. How many users are troubled by issues such as electrical leakage, burning of computer hosts, and explosion of mobile phones, and how many products have been delayed from being launched due to failure to pass safety testing. The diversification and complexity of problems have led to the rapid development of circuit protection components, and today's protection devices have developed into a diverse emerging field of electronic components. Faced with such a complex and diverse field, we have many questions. What is the development trend of protective devices? What parameters should application engineers choose appropriate protective devices based on? What factors should be considered in circuit design? How to handle failure analysis when encountering a faulty machine? In response to these issues, W
SMD chip fuses have been very popular in the domestic market in recent years, and they are on par with plug-in fuses. However, due to their small size and other advantages, SMD chip fuses have gradually occupied a place in daily life. Now, I will briefly explain the market prospects of SMD chip fuses. In its over 100 year history, small fuses have gone through multiple stages of development, including cylindrical, plug-in, axial or radial pin types. The surface mount fuse, which emerged in the 1990s, has developed to account for nearly 30% of the overall small fuse application market in less than 20 years, and is continuously expanding, replacing other traditional forms of fuses, indicating its strong vitality. With the vigorous development of the electronic industry, the small fuse market is showing a continuous growth trend, especially in 2015, where the development momentum is encouraging. The development of surface mount fuses is increasing day by day, accounting for one-thir
Firstly, understand the function of fuses: Place the circuit fuse correctly. Then, the fuse will rise to a certain height and after a certain period of time, the fuse will cut off the current, thus protecting the operation of the circuit. The principle of patch fuses is the same, but the style is different. Below, we will have a detailed understanding: Chip fuses are mainly used in electronic products such as digital cameras, laptops, and smartphones. Due to differences in product technology, the selection focus varies from traditional glass tube fuses to micro fuses and chip fuses. The selection of chip fuses involves the following factors: The normal operating current of the circuit. The working current through the fuse should not exceed 70% of the rated current of the fuse. Pulse, surge current, surge current, starting current, and circuit transient. Chip fuses pay special attention to the following facts: due to the small process size, the impact resistance of chip fuses is
I hold current I hold, high non operating current (maintenance current), refers to the high current that PPTC always maintains its low resistance state at the specified ambient temperature (priority 25 ℃). I hold: maintain current; V max: withstand high voltage; T trip: specifies the large action time under the current; R: Zero power resistance measured at a certain temperature; I trip: action current; I max: The maximum current that can be withstood; P d: steady-state power consumption in high resistance state; R 1max.: The high resistance value measured at room temperature after one hour of action or soldering. Let's take a look at the internal structure of the device, as shown in Figure 4. Place the test sample in a specified temperature and condition test box, connect the PPTC to a constant current or constant voltage source, and preset the current value to the specified I hold, with the voltage limited to 90% of V max. After the specified time in the detailed specifi
Chip fuse is a relatively high-tech new variety in the small fuse industry. Chip fuse can be divided into disposable chip fuse and chip self recovery fuse. Disposable chip fuse, also known as chip current fuse, needs to be replaced after protection, and after self recovery fuse protection, power is cut off, it can be restored on its own and can be reused. The disposable patch current fuses can be divided into the following models based on size and performance: (1) According to size, products can be divided into: 0402, 0603, 1206241061251032. (2) According to performance, products can be divided into three types: fast melting, slow melting, and enhanced melting heat energy. The SMD fuse quick blow series is suitable for protecting important components that quickly respond in circuits, and is generally used in situations where surge currents rarely occur; The slow fuse series is suitable for situations where large surge currents often occur in circuits; The enhanced melting heat e
