Introduction of Surface Mount Fuses
Surface mount fuse is a widely used protective component in electronic circuits.
Structurally speaking, patch fuses are compact in size and typically flat in shape. They are designed to be suitable for surface mount technology (SMT) and can be easily installed on printed circuit boards (PCBs). This compact structure gives it a unique advantage in the trend of miniaturization in modern electronic devices, effectively saving space on circuit boards.
Its working principle is based on the thermal effect of electric current. When the current in the circuit exceeds the rated current of the patch fuse, the resistance wire inside the fuse will heat up, and as the heat accumulates, the temperature of the resistance wire will rapidly rise. When the temperature reaches the melting temperature of the fuse, the resistance wire will melt, thereby cutting off the circuit and protecting other components in the circuit.
In terms of application fields, patch fuses are very common in various consumer electronic devices, such as smartphones, tablets, laptops, etc. The circuit board space of these devices is limited, and patch fuses can provide reliable overcurrent protection without occupying too much space. Meanwhile, in some industrial control equipment and automotive electronic systems, patch fuses are widely used due to their stability and reliability.
However, patch fuses also have certain limitations. Due to its small size, the current and power it can withstand are relatively limited. In some situations where high current protection is required, other types of fuses or protective devices may need to be used.

Encapsulation Forms of Current Fuses
The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.
Explanation of Parameters in the PPTC Specification for Self Healing Fuses
This is very simple. As long as you know the meaning represented by the parameters in the specification book, you can clearly and quickly view the PTC specification book for self recovery fuses.
Professional Knowledge of Self-healing Fuses
The operating principle of a self-healing fuse is a dynamic balance of energy. The current flowing through the self-healing fuse generates a certain amount of heat due to the thermal effect of the current (self-healing fuses all have resistance values), and the generated heat is completely or partially dissipated into the environment. The heat that is not dissipated will increase the temperature of the self-healing fuse components. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance.
The Role of Current Fuses in Smart Meters
Current fuses play a vital role in smart meters. Firstly, they provide protection against overcurrent events. Smart meters are used to measure and manage electricity consumption accurately. However, electrical circuits can sometimes experience sudden surges in current due to various reasons such as power outages and subsequent restoration, short circuits in the electrical grid, or the malfunction of connected electrical appliances.

Essential Knowledge for Selecting Automotive Fuses
When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase； When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circuit.
Several Factors Influence the Lifetime of Current Fuses
The lifetime of a current fuse is influenced by several factors. Firstly, the current rating of the fuse plays a crucial role. If a fuse is constantly operating near or at its rated current, it will experience more heat buildup and stress over time, which can shorten its lifetime.
