Power switch thermistor case

Customised thermistor by Jiangsu Yufeite special electronic, compared with other thermistor manufacturers, Yufei special thermistor products with high power, strong ability to inhibit inrush current, high reliability, long life, small residual resistance, etc., is a cost-effective, high reliability power type.As the switching power supply has high efficiency, energy transmission loss is small, the output is flexible and variable, occupies a small volume and space and other general linear power supply are incomparable advantages and won a wide range of applications. Nowadays, large to large electronic equipment power supply, small to home appliances, LED lamp power supply almost without exception are used to switch-mode power supply, it is the current more unanimously recognised high-efficiency, low-power power supply mode. But low-power, high-efficiency conversion (AC-DC) is the price, switching power supply in practical applications will also produce a lot of trouble, such as: EMC problems start-up inrush current problems, high-voltage high-current situation, with high value of key components are prone to frequent damage, early failure of the phenomenon of the entire power supply system premature damage to devices or equipment can not be used. This is the majority of line designers, especially power supply design engineers one of the most headaches, the current impact in the switching power supply end, choose the appropriate power type NTC, effectively solve this problem
