保险丝> 表面贴装保险丝> 扁平封装保险丝> 202

可提供Flat-Pak®保险丝设计的快熔型和Slo-Blo®型号。这两种设计

均采用鸥翼式表面贴装封装或适合通孔封装的DIP结构。  此类设计的

电压额定值为250伏交流，并采用小尺寸矩形封装。

Fast-Acting and Slo-Blo® Fuse versions of the FlatPak® Fuse designs are available. 

Both designs are available in either a gull-wing surface mount package or a DIP 

configuration for through-hole mounting. These fuse designs feature a 250 VAC 

rating in a low profile, rectangular package.

When the material and shape of the fuse are determined, its resistance R is relatively 

determined (without considering its resistance temperature coefficient). When the 

current flows through it, it will heat up, and the calorific value will increase as time 

goes on. The size of the current and resistance determines the speed of heat generation. 

The structure of the fuse and the condition of its installation determine the speed 

of heat dissipation. If the velocity of heat is less than the speed of heat dissipation, 

the fuse will not fuse. If the rate of heat generated is equal to the rate of heat 

dissipation, it will not fuse for a long time. If the speed of heat generation is greater 

than that of heat dissipation, the amount of heat generated will be more and more. 

Because it has a certain heat and mass, the increase of heat is shown in the rise of the 

temperature, and the fuse breaks when the temperature rises above the fuse point. 

That's the principle of the fuse. We should know from this principle that you must 

carefully study the physical properties of the materials you choose and make sure 

they have a uniform geometric size when designing and making fuses. Because these 

factors play an important role in the normal operation of the fuse. Similarly, when you 

use it, you must install it correctly.
