Temperature Sensors - NTC Thermistors

The NTCS0402E3473FXT is a negative temperature coefficient (NTC) thermistor used as a temperature sensor. It is a passive device with a ceramic composition that has a predictable electrical resistance to temperature. This particular component is made by Hoyao Electronic and is a 4-Pin device, with shielded leads that have a diameter of 0.89 and a length of 8.6. It is a small device measuring just 0.04 by 0.02 inches.

Application Field

This type of thermistor is ideal for applications such as temperature sensing and as a current-limiting device in power supplies. It can be used for surface temperature measurements in enclosed systems, as it is able to accurately measure the temperature of heated processes or objects. Furthermore, it is offered in both leaded and non-leaded formats, making this thermistor suitable for a wide range of applications in the industrial, automotive and consumer electronics market segments.

Working Principle

NTC Thermistor operates on the principle that a material’s resistance to electric current rises with its temperature. This phenomenon is called the Peltier-Seebeck effect and is the basis of its functionality. By applying a current, the thermistor changes its temperature which is then sensed and a voltage is generated which can be interpreted as temperature. The NTCS0402E3473FXT has a negative temperature coefficient (NTC) that also reduces the device’s power consumption as temperatures increase, making it a great choice for temperature sensing applications.

This thermistor is typically used in conjunction with a temperature-sensitive device, such as a control circuit, to create accurate temperature-sensing applications. The NTCS0402E3473FXT has an exceptional operating temperature range of -55°C to +150°C and includes nickel barrier terminals to withstand heat, shock and vibration, making it ideal for extreme environment applications.

The thermistor also features excellent linearity and accuracy, making it suitable for precision temperature-sensing applications. This is especially important for products using automotive electronics and other precision applications such as consumer electronics and medical devices. The thermistor also has a low self-heating, making it suitable for applications requiring precise and reliable temperature-sensing with minimal power consumption and zero warm-up times.
