Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to a rectifier bridge stack with an integrated thermistor. Background Art

[0002] Power conversion and protection circuits are essential components in modern electronic devices. Traditionally, these circuits consist of two key components: a bridge rectifier and a thermistor. The bridge rectifier converts AC power to DC, while the thermistor provides temperature sensing, overtemperature protection, and inrush current suppression. However, these two components are typically used as separate components and mounted separately on the circuit board, resulting in complex board layouts and a large footprint.

[0003] In existing circuit designs, the bridge rectifier and thermistor each occupy a certain amount of space, increasing not only the size of the circuit board but also the manufacturing cost. Furthermore, since these two components are not integrated, signal transmission and coordination between them are inconvenient, affecting the reliability and efficiency of the entire circuit. This separate design approach is particularly disadvantageous given the trend towards miniaturization and high-density integration. Utility Model Content
