WRE-230 WRE-231 WRE-221 WRE-222 WRE-223 assembly thermocouple
Product introduction:
WRE-230 WRE-231 WRE-221 WRE-222 WRE-223 assembly thermocouple, we all know that there are many types of tunable resistors. No matter what kind of tunable resistors are used and precautions in the process of use, we should pay attention to and understand. Different tunable resistors may work during use. They are also different. Today we will simply analyze the main characteristics of the vertical adjustable resistance. However, in the analysis of the performance characteristics, what is the meaning of the adjustable resistance symbol. Everyone may not understand. The specific details as follows:
Analysis of performance characteristics of vertical adjustable resistors
Adjustable resistors can be divided into: plug-in adjustable resistors and patch adjustable resistors according to different installation methods. However, plug-in adjustable resistors are divided into: vertical adjustable resistors and horizontal adjustable resistors, but they each have their own The advantages and disadvantages, let's look at the details:
1. Vertical adjustable resistance: The PCB area is required to be small, which can reduce the space occupation. Components are slightly less robust. Such as semiconductor radio. The process is relatively simple, the cost is low, and it can even be welded by hand.
2. SMD adjustable resistance: The heat dissipation problem is not serious, which requires less space. The process is complicated and the cost is high. Such as computer hard drive circuit boards.
3. Horizontal adjustable resistance: The installation space is relatively wide, and the components are required to be installed firmly and reliably, and the heat dissipation is good. For example TV main circuit board. Generally it is automatic wave soldering.
