The MF72 Series Power NTC Thermistor from Nanjing Shiheng Electronics Co., Ltd. is designed for current limiting applications. It features a green silicone resin encapsulation, offering high temperature resistance (up to 300C), rapid heat dissipation, and good insulation. This series is ideal for applications requiring surge current suppression. Despite potential surface friction marks and minor cracks at the lead pins due to material properties, these do not affect the product's performance or reliability.
