SM403J1K

Temperature Sensors - NTC Thermistors

NTC thermistors are commonly used in temperature sensing applications. SM403J1K is a special type of temperature sensor, a negative temperature coefficient (NTC) thermistor. It is designed with two resistance-temperature characteristics used in temperature sensing applications.

Application Field

The SM403J1K NTC thermistor can be used as temperature sensors in many areas, such as:

• Automotive industry – engine control, engine management and air conditioning systems.
• Medical industry – patient temperature monitoring systems.
• General industrial applications – temperature monitoring and control.
• Home and leisure industry – oven and refrigerator temperature monitoring.

Because of their small size and high accuracy, NTC thermistors are suitable for use in many different applications where temperature sensing is required.

Working Principle

The SM403J1K NTC thermistor works on the principle of negative temperature coefficient (NTC). The resistance of the thermistor decreases as the temperature increases. This property of the thermistor makes it suitable for temperature sensing applications.

The resistance of the thermistor is measured by connecting a resistance measurement circuit to the thermistor. The resistance measurement circuit measures the resistance of the thermistor and then converts it to a temperature reading. This measured temperature can be used to control the operation of a device or to inform the user about performance.

The SM403J1K NTC thermistor has a wide operating temperature range, so it can be used for temperature sensing in many different applications. It is also resistant to vibration and shock, so it is suitable for use in harsh environments.
