When an overload occurs, a disposable fuse will blow at once. Although it can provide overcurrent protection, it needs to be replaced. The core part of a conventional fuse is a section of wire, which is heated to the melting point when the current is too high. After the wire melts, the current in the circuit drops to zero. So in some circuits that require complete power outage, or products with higher risk factors such as machinery, it is more suitable to use disposable fuses, which has a higher safety factor when used. Both traditional disposable fuses and self restoring fuses can achieve overcurrent circuit protection. Both achieve protection by reacting to the heating phenomenon generated by excessive current in the circuit. Fuses break the current by blowing, while self restoring fuses rely on changing from a low resistance state to a high resistance state to limit the magnitude of the current. There are two optional types of self recovery fuses and disposable fuses available
The fusing current of patch fuses is 1.5 to 2.0 times the rated current. When electrical equipment is in normal use, its fuse will not blow. When the current in the circuit exceeds 5 times its rated current, it will automatically fuse to provide protection. If the fuse of the electrical equipment blows during normal use, it indicates that the current in the circuit exceeds the rated value. Therefore, the cause should be promptly investigated. During the installation process of patch fuses, it is necessary to first pull off the switch on the distribution board, cut off the power supply, and preferably use an electric pen to test whether there is power before operating. For fixing screws and washers, copper should be used instead of temporary iron, as iron can easily rust over time and lead to poor contact. When tightening the fuse, do not use too much force to prevent the fuse from being flattened and causing a decrease in cross-sectional area, rated current, and fusing current, wh
During the operation of some product circuits, static electricity can be generated, which poses a great threat to some high-speed circuits. PGB fuses are needed to provide ESD protection (static electricity protection) for product circuits that are prone to static electricity. For example, products such as high-definition televisions, IPTV receiving devices, and set-top boxes that generate static electricity during high-speed operation can directly damage the internal chips of the product through exposed connectors or data cables, making it difficult to restore the internal chips of the product. How is the Lite PGB fuse protected from static electricity? The Lite PGB fuse can instantly transition from a high resistance state to a low resistance state, releasing the surge generated by static electricity to the ground. It maintains consistency in both high and low frequencies and has strong anti-interference ability. Compared with other products, Lite PGB fuse has better electrostat
In electronic products, chip fuses have two functions: protecting end users from harm and protecting circuits from damage. These functions benefit both device users and manufacturers. Over the past decade, the demand for electronic devices serving information technology, mobile, and consumer applications has sharply increased in the market. With this rapidly growing demand, the risk of unexpected situations in electronic devices has also increased, requiring the use of overcurrent protection devices such as chip fuses to avoid risks such as electrical overload. Before analyzing the electrical characteristics of various chip fuses in the market, it is first necessary to understand the basic design principles behind each technology. Standard fuses may be based on metal wires placed inside sealed ceramic or glass tubes filled with air or sand, but chip fuses are based on completely different principles. Most chip fuses appear to be standard chip devices and are made of single or mul
With the development of technology, there are more and more components in circuit design, so the requirements for electronic component packaging are becoming smaller and smaller. The 0603 SMD fuse emerged in this context. The 0603 chip fuse provides ultra fast action fusing characteristics in a smaller chip size. The rated current value of the device is up to 4.0A, and its breaking capacity is 35A at a rated voltage of 32V. The 0603 fuse adopts standard metric dimensions (91.55mmx85mmx45mm) and can provide secondary overcurrent protection for low-voltage power supplies in DC-DC converters, battery chargers, and portable consumer electronic devices. Through strictly controlled manufacturing processes and advanced thick film technology, fuses provide excellent long-term stable fusing characteristics for portable devices such as mobile phones, PDAs, digital cameras, cameras, and LCD flat panel displays. The halogen free and lead-free 0603 chip self recovery fuse supports lead-free
Disposable fuses can be divided into fast fuse and slow fuse. The models of disposable slow fuse available in Jidian Tong brand include: slow break JFC0603, slow break JFC1206, and slow break JFC2410. A one-time slow blown fuse, also known as a delay fuse, has a delay characteristic characterized by its ability to remain intact during non fault pulse currents in the circuit and provide protection against prolonged overload. Some circuits have a current that is several times greater than the normal working current at the moment of switching. Although this current peak is high, it appears for a short time. We call it pulse current, also known as impulse current or surge current. Ordinary fuses cannot withstand this current, and if a regular fuse is used in such a circuit, it may not be able to start normally. If a larger specification fuse is used, it will not be protected when the circuit is overloaded. The melt of the delay fuse is specially processed and has the function of absor
