Surface Mount Fuse, a Widely Used Protective Component in Electronic Circuits
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.
