Temperature Sensors - NTC Thermistors are widely used for applications in various fields, and the 135-103LAF-J01 is no exception. Used in a variety of different applications including temperature control, timing, and power switching, it has become an integral part of many systems. This article will discuss the application field and working principle of the 135-103LAF-J01.

The 135-103LAF-J01 is a negative temperature coefficient NTC thermistor, which is an electronic resistor whose resistance varies inversely with temperature. This means that when the temperature increases, the resistance decreases, and vice versa. This thermistor can operate over a wide temperature range of -40 to 250 °C, making it an ideal candidate for use in a variety of applications.

Temperature sensing is a common application of the 135-103LAF-J01. It is often used in systems that require precise temperature control, such as air conditioners, heater control systems, and ovens. The thermistor allows the system to detect sudden changes in temperature and adjust accordingly. It can also be used to detect and monitor changes in the ambient temperature. This is useful for applications such as weather forecasting and environmental monitoring.

The thermistor can also be used for timing applications. It can be used to detect the temperature of an object or environment and activate a timing mechanism that can set a specific time limit. This is useful in applications such as a timer for a gas stove, where it would be used to accurately turn off the stove at a specified time. The thermistor can also be used to help with power switching systems. It can detect the temperature of a power switch and adjust its settings according to the ambient temperature. This is useful for applications such as LED lighting control systems, where the thermistor can help ensure that the system does not overheat and damage the LEDs.

The working principle of the 135-103LAF-J01 thermistor is based on the fact that as temperature increases, the resistance of an NTC thermistor decreases. This is because as the temperature increases, the molecules inside the thermistor vibrate faster, which causes them to move further apart, and this in turn reduces the electric field between them. As a result, the resistance of the thermistor decreases. Conversely, when the temperature decreases, the molecules slow down and move closer together, increasing the electric field and therefore increasing the resistance.

In order for the thermistor to be effective, it needs to be properly calibrated. This involves setting the reference voltage and the temperature at which the reference voltage will be reached. This can be done with a thermocouple or an analog-to-digital converter. Once the thermistor is set up and calibrated, it can then be used to accurately measure the temperature of an object or environment.

In conclusion, the 135-103LAF-J01 thermistor is a widely used NTC thermistor that is used for a range of applications in different types of systems. It is an excellent choice for temperature control, timing, and power switching applications due to its wide temperature range and ability to accurately measure temperature. Its working principle is based on the fact that as temperature increases, the resistance of an NTC thermistor decreases. In order for the thermistor to be used properly, it needs to be calibrated first in order to set the reference voltage and temperature.
