NTC thermistors, or negative temperature coefficient thermistors, are electronic components that have a resistance that changes as the ambient temperature changes. The B57045K0103K000 is a type of NTC thermistor and is widely used in temperature sensing applications.

NTC thermistors consist of two major components: a resistor and a temperature sensitive semiconductor. The resistor construction is usually a mix of polymers and ceramic materials sealed inside a metal or plastic housing. As the temperature increases, the resistance of the resistor increases. This is due to the fact that the semiconductor reacts to temperature changes in a negative manner. The semiconductor converts thermal energy into electrical energy, which activates the resistor. The higher the temperature, the more active the resistor becomes.

In the B57045K0103K000, the resistor is made of copper wire and has a resistance range of 18.2 to 33.3 ohms. This particular thermistor is used in a variety of temperature sensing applications, such as temperature measurement for medical equipment, automated process control systems, industrial ovens and furnaces, and home appliances. It is also used in automotive engines to monitor the engine temperature.

In addition to its use in temperature sensing applications, the B57045K0103K000 can also be used for overload protection in electronic circuits. In overload protection applications, the thermistor is connected to an external current-limiting circuit. During an overload, the thermistor will heat up and increase its resistance, thus limiting the current flow. This helps protect sensitive components in the circuit from damage due to excessive current.

The B57045K0103K000 is a robust and reliable thermistor that can be used in a variety of temperature sensing applications. It has an operating temperature range of -40°C to +125°C and can handle up to 1 Watt of power. The thermistor is also resistant to moisture, vibration and shock. It is available in surface-mount and through-hole packages, making it easy to install in a variety of electronic systems.
