CWF1B103F3380

Temperature sensors come in many shapes and sizes. One of the most popular for industrial and commercial applications is the NTC thermistor. NTC Thermistors are solid-state temperature sensing devices. They are non-linear resistive elements which respond to changes in temperature with changes in their electrical resistance. The CWF1B103F3380 is one of the most popular NTC thermistors for temperature sensing.

CWF1B103F3380 Application Field and Working Principle

CWF1B103F3380 is an encapsulated NTC thermistor designed with two wire leads, which is suitable for high temperature applications but not recommended for soldering purposes. Common applications of the CWF1B103F3380include temperature monitoring and control in industrial and commercial HVAC systems, as well as in air conditioning, fire alarm, household appliances, medical and automotive temperature sensing applications. The thermistor also has a wide range of temperature measurement/control capabilities, with a temperature range of -20°C (68°F) to 160°C (320°F).

NTC thermistors are designed to be temperature sensitive devices. Their resistance values are dependent upon the temperature of their environment. As the temperature increases, the resistance of the thermistor decreases, and conversely, as the temperature decreases, the resistance increases. This is referred to as the “base resistance”. The exact resistance of the thermistor is affected by the material type used, with some materials exhibiting a more pronounced decrease in resistance than others. The CWF1B103F3380 is made from a Nickel-Cobalt-Manganese(Ni-Co-Mn) material type.

When the NTC thermistor is used in a circuit, it is connected in series with a current source and the resistance of the thermistor is measured across a load resistor. The current flows through the thermistor and across the load resistor according to Ohm’s law. When the temperature changes, the resistance of the thermistor changes, thus causing a change in the current flow through the thermistor. The magnitude of the current change is proportional to the magnitude of the temperature change.

The CWF1B103F3380 is a precision NTC thermistor, designed with superior stability and repeatability. It is built with a thermistor element that has a low initial resistance and small temperature coefficient. It is designed with a 2-wire leads that allows for an easy connection with any type of control unit. It is also constructed with an encapsulated molded aluminum can to protect the device from dust and vibration. The CWF1B103F3380 is UL, CUL, and CE approved for use in industrial and commercial temperature sensing applications.

In summary, the CWF1B103F3380 is an extremely popular encased NTC thermistor designed for use in high temperature applications. It is a precision device, with a low initial resistance and small temperature coefficient. Its two-wire design makes it easy to install and connect to any type of control unit. With a wide range of temperature measurement and control capabilities, it is UL, CUL, and CE approved for use in industrial and commercial temperature sensing applications.
