What Are the Differences Between Varistors and Thermistors? Unikeyic Explains

Electronic components are classified in great detail, but users often confuse similarly named products when purchasing them, which affects the speed of procurement. Varistors and thermistors, for example, are frequently mixed up. To ensure accurate completion of procurement tasks, it's essential to understand the differences between these two types of electronic components. Let's see unikeyic's, explanation.

1 Differences in Sensitivity

One key difference between varistors and thermistors is their sensitivity. These two products have different electrical properties, leading to varying levels of sensitivity. Varistors are more sensitive to voltage, allowing them to protect circuits effectively. In contrast, the resistance value of thermistors changes with temperature, making them highly sensitive to operating temperatures.

2 Differences in Application Circuits

According to the information available on Unikeyic, the application circuits for varistors and thermistors also differ. Thermistors are typically used in series with a circuit board because of their high sensitivity to operating temperatures. They will automatically fuse in high-temperature environments, preventing the circuit from being damaged by heat. Varistors, however, are directly installed on the circuit board. When the voltage increases, the varistor provides voltage protection for the circuit board.

3 Differences in Usage Requirements

Due to the significant differences between varistors and thermistors and their distinct functions, user requirements for these products also vary. When purchasing electronic components, users should choose thermistors or varistors based on their specific needs.The differences between varistors and thermistors are quite pronounced. Understanding these differences will help you develop a more effective procurement strategy. You can use Unikeyic to filter and select high-quality electronic components that meet your requirements.By distinguishing between varistors and thermistors, you can make informed decisions during the procurement process and accurately select the appropriate high-quality electronic components from Unikeyic.
