Temperature Sensors – NTC ThermistorsNTC thermistors are thermally sensitive resistors, designed to produce a precise and repeatable change in resistance when subjected to a temperature change. The NHQ304B435T5 thermistor is a negative temperature coefficient thermistor, meaning that the resistance of the thermistor decreases when its temperature increases.ApplicationsNTC thermistors are used in many different applications as temperature sensors, controllers, or over-temperature protectors. The NHQ304B 435T5 is ideal for applications that require medium accuracy and rapid temperature sensing and where the operating temperature range is between -40 and 150°C. Common applications for this type of thermistor include temperature monitoring in appliances, such as refrigerators, freezers, and ovens; temperature control in water and air-conditioning systems, as well as temperature sensing in medical and laboratory equipment.Working PrincipleThe working principle of the NHQ304B435T5 thermistor relies on a predictable, repeatable reduction in resistance when exposed to an increase in temperature. This thermistor has an NTC characteristic, meaning that its resistance decreases with an increase in temperature. The greater the change in temperature, the greater the corresponding change in resistance, making the thermistor ideal for applications such as temperature compensation.As temperature increases, the thermistor’s resistance decreases. This decrease, or change in resistance, can be highly precise, meaning the thermistor can be used to control temperature with a great degree of accuracy. The thermistor’s performance is dictated by its material composition, with semiconductive ceramics containing metal oxides being a popular choice.ConclusionThe NHQ304B435T5 thermistor is a popular NTC thermistor used in many temperature sensing applications such as appliances, water and air-conditioning systems, and medical and laboratory equipment. Its predictable and repeatable decrease in resistance makes it ideal for temperature control and compensation due to its highly precise response when exposed to an increase in temperature.
