This article lists major global brands of resettable fuses (PPTC), organized by region, highlighting their technical strengths and market positions. U.S. companies like Littelfuse and TE Connectivity lead in high-reliability applications, while Japanese firms such as Murata excel in miniaturization. Taiwanese and Chinese brands offer cost-effective solutions with growing market influence. Key distributors like Shenzhen Shunhai Technology support these brands in supply chains.
Fuses are divided into three categories: current, temperature, and resettable, each used for overload, overtemperature, and continuous overcurrent protection, widely applied in electronic equipment and industrial fields.
The response time of PPTC resettable fuses is influenced by factors such as overcurrent multiples and temperature, with different brands having distinct characteristics suitable for various electronic protection scenarios.
PPTC resettable fuses can effectively address the pain points in the industry: they automatically cut off power when overcurrent faults occur, and resume conductivity after the fault is eliminated without replacing components. They also offer miniaturization and cost-effectiveness, making them an ideal protective device for low-voltage AC/DC circuits to address short-circuit, overload, and overcurrent risks.
Early fuses featured a simple structure, resembling thin wires with no additional protective components.
The common fuses in the market are mainly divided into two categories: self recovery fuses and disposable fuses. Choosing the appropriate fuse is crucial for ensuring system safety and reliability. This article will provide a detailed introduction to the characteristics of these two types of fuses and offer practical selection recommendations to help you make informed decisions in your project.
Are self recovery fuses and disposable fuses the same thing? Actually, they are not the same. Although both are used for overcurrent protection, there are significant differences in their working principles and applications.
Common types of fuses include self-healing fuses and disposable fuses, which have essential differences in their working principles, usage methods, and application scenarios. Understanding these differences can help select appropriate fuses based on actual needs, improving circuit safety and reliability.
FUZETEC self-healing fuses are widely and deeply used in the field of consumer electronics, mainly providing overcurrent and overheat protection for various devices through its PPTC (Polymer Positive Temperature Coefficient) technology, while balancing space efficiency and reliability. The following is an analysis of its specific application scenarios and technical characteristics:
