Thermistor related applications

1. Using a thermistor in the battery circuit, you can detect excessive current or current overheating to adjust the rate of charging. As a result, the current at the time when the battery starts to be charged is relatively large, so that it can be quickly charged with a large charging current in a relatively short period of time. When the critical current or critical temperature is to be reached, the charging speed can be controlled to be lowered, and then the charging can be completed relatively smoothly.

2. The smaller and smaller size of notebook computers has also challenged engineers. The motherboard of the computer is very sensitive to temperature, and the motherboard is very close to the heating power circuit. The increasing CPU frequency not only increases the speed of the CPU, but also makes it work at a higher temperature. In this case, the surface-mount thermistor can be quickly responded to overheating and is easier to use, but sometimes the thermistor cannot be mounted in the desired position. The combination of a surface-encapsulated thermistor in a specially shaped stripline places the temperature-sensitive component at a specific point of sensitivity, further enhancing the protection.

3. The food and pharmaceutical industry also uses temperature control during transportation to ensure product quality. In order to prevent some or all of the loss of the use of the drug, many drugs have to accurately control the temperature and temperature during transportation. The temperature recorder continuously manages the conditions of transportation during transportation. A typical recorder may be a set of test cards placed in different locations, which may include an internal thermistor assembly, an external thermistor probe, or both.
