NTC thermistors, also called Negative Temperature Coefficient thermistors, are temperature sensors usually made of semi-conductive ceramic materials that exhibit a decrease in electrical resistance when exposed to an increase in temperature.

ERT-J1VK102FM is a NTC thermistor specifically designed for applications in which an accurate temperature measurement is required. It has a broad temperature range from -50 °C to +150 °C with an operating voltage of DC 5 V.

In an ERT-J1VK102FM, the resistance decreases with the increase in temperature, which means that when a current is passed through it, the voltage across it changes with the temperature around it. This electrical current-voltage relationship is known as the Seebeck effect.

It works by passing a DC current through a thermistor body and measuring the voltage across it. The voltage is proportional to the temperature of the thermistor. This method is known as the voltage output method.

To calculate the ambient temperature, the output voltage of the thermistor is compared to a reference voltage which is generated by an internal temperature-sensitive reference source. The difference between these two voltages is referred to as the ‘Net Voltage’ which is then amplified by an amplifier which amplifies the signal to a low-level voltage.

The amplified signal is then further processed by a microprocessor, which is capable of calculating the temperature from the net voltage. This temperature data is then sent to the controller and can be used for various purposes such as monitoring, controlling, and adjusting the temperature.

The ERT-J1VK102FM is often used in many applications including automotive, aerospace, and industrial systems. It is reliable due to its high accuracy, low power consumption, and low temperature coefficient. It can be used in many different types of temperature measurement and control applications such as cooling, heating, and refrigeration systems.

In addition, it can also be used with other products such as electronic thermostats, burglar alarms, ovens, and other consumer electronics. This thermistor is also suitable for use in medical applications such as defibrillators and pacemakers. The high accuracy of this thermistor makes it an ideal choice for many applications.

The working principle of the ERT-J1VK102FM is based on the Seebeck effect, which states that when a current is passed through a material, the voltage across it changes when the temperature around the material changes. By monitoring and measuring this change in voltage, the ambient temperature can be calculated. This thermistor is designed to be highly accurate and reliable, making it a popular choice for temperature measurement and control applications.
