Description
WMZ75S is the model number of the PTC (Positive Temperature Coefficient) thermistor. A PTC thermistor is a semiconductor device with a positive temperature coefficient, and its resistance value changes depending on temperature.
1. PTC thermistors have a positive temperature coefficient where their resistance increases as temperature increases. This means that the thermistor can perform the temperature sensing and protection functions used to control resistance.
2. WMZ75S PTC thermistor provides high-precision temperature sensing. This allows temperature changes to be quickly detected and the necessary actions to be taken in control or protection circuits based on this.
3. PTC thermistor can perform protection functions such as overheating protection, overcurrent protection, and overload protection. This means that electronic devices and circuits can support safe operation and protect against potential overheating or overcurrent.
