SM72480SD-120/NOPB

Temperature sensing is an important application in many industries. Solid state thermistors are one of the most common methods of sensing temperature. The SM72480SD-120/NOPB is a thermistor that is designed for temperature sensing and time-over-temperature protection applications. It provides a wide range of temperature sensing, with a 6.4-k W nominal resistance at 25˚C, and an operating environment of -40˚C to +85˚C.

This thermistor is a solid-state device consisting of two distinct components; a temperature sensing element and a circuit protection element. The temperature sensing element is a ceramic substrate with a metallic film deposited onto it which results in a PTC behavior. The circuit protection element is a small electrical switch, which is connected in series with the thermistor element.

The SM72480SD-120/NOPB operates on the Resistive Temperature Detector (RTD) principle, which explains the rotational behavior of the resistance values in relation to the temperature. The temperature sensing element has a positive temperature coefficient, which means that the resistance of the element will rise with increases in temperature. As the temperature rises, the resistance reaches a point where it triggers the circuit protection element, and the thermistor switches off allowing it to function as a temperature-over-time protection device.

The SM72480SD-120/NOPB has a wide range of applications in temperature sensing and time-over-temperature protection. The device is suitable for use in a variety of industrial applications, such as electrical safety, electronic device protection, temperature regulation and monitoring, and industrial process control. The thermistor is also suitable for agricultural applications, including climate control for greenhouses and crop management. The thermistor is also commonly used in consumer applications, such as space heaters, ovens, appliances, and automotive HVAC systems.

The SM72480SD-120/NOPB is an easy to use and reliable temperature sensing and protection device. Its simple yet robust construction and wide operating temperature range make it an ideal choice for many industrial, agricultural, and consumer applications. The thermistor is also cost-effective, provides excellent stability and repeatability of measurements, and has low power consumption, making it an attractive solution for temperature sensing and protection.
