Today, as China is comprehensively building a moderately prosperous society, private cars have become the standard mode of transportation for most households. While earlier models were gasoline‑powered, the newly introduced new‑energy and electric vehicles are now in high demand.
An electric passenger car is a vehicle powered by an on-board energy source and propelled by an electric motor, fully compliant with all road traffic and safety regulations. Electric vehicles can also take advantage of surplus electricity during off-peak nighttime hours to recharge, ensuring that power-generation facilities operate at full capacity around the clock and significantly enhancing their economic efficiency. Moreover, they produce no harmful emissions into the atmosphere, substantially reduce other pollutants, and pose less risk to human health. In addition, power plants are stationary and centralized, making it easier to control and mitigate various harmful emissions.

The MF52 series NTC thermistors are coated with epoxy resin, leveraging advanced materials and manufacturing processes to deliver compact size and fast response. They also feature tight tolerances and long-term stability, ensuring reliable performance. These devices are widely used for temperature sensing, measurement, detection, indicator applications, monitoring, control, calibration, and compensation, making them suitable for HVAC and white goods, automotive, and battery‑pack applications.
Product Usage Precautions:
Avoid measurement errors caused by self-heating and excessive current passing through the thermistor chip.
When soldering with a soldering iron, ensure the solder joint is at least 2 mm away from the coating; the soldering temperature should be below 300°C, and the soldering time should be less than 3 seconds.
The product shall be stored at ambient temperatures ranging from –10°C to +40°C, with relative humidity not exceeding 75%. The environment must be free of acids, alkalis, corrosive gases, or radioactive sources.
