NB12M00333KBA

Temperature Sensors - NTC Thermistors

The NB12M00333KBA is a negative temperature coefficient thermistor (NTC), which is a temperature sensor. It is a type of resistor whose resistance varies with temperature. NTC thermistors are used to measure temperature in a wide range of applications and environments. They have several benefits over other types of temperature sensors, including low cost, high accuracy, small size, no emissions, and a linear temperature response.

Application Field

NTC thermistors are used in a wide range of applications, including automotive, industrial, medical, and consumer electronics. In the automotive industry, they are used in anti-theft systems to detect a sudden change in temperature, such as someone breaking into a car. They are also used in temperature monitoring to ensure engine temperature remains within an acceptable range. In industrial applications, they can be used to monitor environmental conditions in order to provide reliable performance. In medical monitoring, they are typically used for patient temperature monitoring applications. Lastly, in consumer electronics, they are often used in air conditioners, refrigerators, ovens, and other home appliances, as well as in handheld and wearable devices in order to monitor temperature accurately.

Working Principle

NTC thermistors work by sensing a change in temperature and measuring the corresponding change in electrical resistance. As temperature increases, the resistance of an NTC thermistor decreases. Similarly, as temperature decreases, the resistance increases. This relationship is due to the fact that with higher temperatures, the molecules in the thermistor move faster and take up less space, thus decreasing the resistance. Conversely, with lower temperatures, the molecules move slower and take up more space, thus increasing the resistance.

The NB12M00333KBA is an NTC thermistor with an operating temperature range of -40°C to +85°C. It is characterized by a B value of 3380 K and a resistance of 10 kilohms at 25°C. This thermistor is designed for high-temperature sensing applications and can be used to accurately measure and control temperatures in a variety of environments.
