    In the field of power tools, NTC surge current limiters are widely used in various types of tools to ensure their safety and reliability. This article will focus on the application of NTC inrush current limiters in a tool called an electric angle grinder.

    An electric angle grinder is a tool used for grinding and cutting metal, stone and other materials. It has the characteristics of high speed and high power. Since it operates on a power source, the tool may be exposed to surge currents in the event of power voltage fluctuations or power interference.

    To prevent this from happening, NTC surge current limiters are used in electric angle grinders. This NTC is installed in the power supply protection circuit to limit the inrush current in the power supply. When power supply voltage fluctuations or power interference occur, NTC will act immediately to limit the inflow of surge current through its resistive characteristics and protect the tool's electronic components from damage. Under the protection of NTC, the electric angle grinder can work safely and smoothly, providing users with efficient and precise processing services.

    It is worth mentioning that the NTC surge current limiter can also improve the service life and stability of the electric angle grinder. With NTC, the tool's power protection circuit can better protect the electronic components of the electric angle grinder from damage, thereby extending the service life of the electric angle grinder. In addition, NTC can also reduce the power consumption and temperature of the electric angle grinder, further improving the reliability and stability of the electric angle grinder.

    In short, the application of NTC surge current limiter in electric angle grinders provides an important guarantee for the stable operation of electric angle grinders. In future power tools, NTC surge current limiters will continue to play an important role in providing users with safer, more efficient, stable and reliable processing services.

​    Nanjing Shiheng Electronics has been committed to the R&D and manufacturing of NTC thermistors. It is a national high-tech enterprise and a national-level "specialized, special and new" small giant enterprise. It has established the "Jiangsu Province NTC Thermal Ceramic Materials Engineering Technology Research Center" , the company relies on its unique process methods and leading technology to produce NTC temperature sensors with outstanding advantages such as high precision, high reliability, and high stability. The power NTC thermistors produced by the company have strong ability to suppress surge impact current and have internal control standards. The maximum capacitance is two levels higher than the standard value, especially the B value is large, the residual resistance is small, the same electrical performance is smaller, the power consumption is lower, and the main power product series has passed UL, TUV, CQC Safety certification, the power thermistor produced by Shiheng Electronics has excellent performance and has been well received by customers!
