NTC Thermistors are a type of temperature sensors, used to measure changes in temperature and consequently have a wide variety of applications. Among these is the 135-503LFW-J01 (coming from the 135 Series of NTC devices from manufacturer Semitec). In this article, we\'ll look at the applications and working principles of this particular NTC Thermistor.

The 135-503LFW-J01 is designed to be mounted on a surface. It is a Low-Fire, Wide temperature range thermistor with a negative temperature coefficient. This allows it to be used for temperature sensing in extreme environments, from -55 to +150°C. The device has a lead-free glass chip and encapsulation so it is suitable for use in lead-free soldering processes.

Typical applications for the 135-503LFW-J01 include power circuit protection, temperature detection in household appliances, motor protection, and thermostats. It can be used in liquid and gaseous environments, as well as solids like plastics, to detect temperature changes. In appliances and electrical circuits, it is used to protect against overheating caused by components such as motors, compressors, and transformers.

The thermistor\'s working principle is based on the fact that depending on the environment, the resistance of the semiconductor material may change. Specifically, as the temperature changes, the resistance changes, according to a known relationship. This means that by measuring the resistance, the thermistor can be used to detect changes in temperature. The 135-503LFW-J01 has been designed to be mounted on a surface, making it ideal for applications such as surface temperature sensing.

The 135-503LFW-J01 thermistor has a range of features that make it suitable for a range of applications. It has an operating voltage range of 25 to 400 VDC, is RoHS compliant, and is ideal for lead-free soldering. The device\'s size (2.5 x 3.6 x 2.2 mm) makes it suitable for use in a variety of applications, from power sources to data centers, both in industrial and consumer applications. Finally, the thermistor is designed to be long lasting and reliable, with a maximum breakdown voltage of 350 VDC.

In conclusion, the 135-503LFW-J01 thermistor is an ideal solution for temperature sensing in extreme environments, and with a variety of features that make it suitable for a range of applications. It is designed to be mounted on a surface, allowing it to be used for surface temperature detection, and has a wide operating voltage range of 25 to 400 VDC. Finally, its small size and RoHS compliance make it ideal for use in lead-free soldering processes.
