NKA103C1R10C is a negative temperature coefficient (NTC) thermistor manufactured by EPCOS. It is a temperature-dependent resistor consisting of a ceramic-metal composite that changes its resistance when temperature changes. NKA103C1R10C has a resistance of 10KΩ±10% at 25℃ and a B value of 3600 K. The tolerance for B value is ±3%.

NKA103C1R10C is widely applied in electronic circuits of all kinds of industrial products, for example, electric furnaces, electric stove, international programmable controls, building temperature controls, and multi-functional industry electronic components. It can be used for regulating temperature, temperature measurement, temperature compensation, temperature control, etc.

The properties of NKA103C1R10C thermistor can be explained by its working mechanism. This thermistor works by using experimentally determined B value. As temperature changes, the energy of bonding between electrons and atoms in the thermistor varies. This will cause a change in conductivity of thermistor, which is inversely proportional to the temperature. Thus, the NTC thermistor can be used as a temperature sensor to determine the temperature change of the environment. The thermistor\'s resistance decreases when the temperature gets higher, as well as increases when the temperature decrease.

The immediate response of thermistor contributes to its stability and reliability. NKA103C1R10C thermistor is usually used in closed loop temperature control systems, such as a cooling fan circuit. When the temperature influencing the hot junction of the thermistor exceeds the preset temperature, the thermistor will reduce its resistance. This will cause the current to flow through the negative feedback loop, and the electric fan will work to release heat. With the decrease in temperature, the electric fan will shut down eventually.

Besides temperature sensing, NKA103C1R10C thermistor can also be used for temperature regulation. This is done by combining other devices, such as operational amplifiers. When an operational amplifier is connected in conjunction with the thermistor, the output current from the operational amplifier can be used to control a relay, which then starts the cooling fan.

The advantages of NKA103C1R10C thermistor include the stability and accuracy due to its fast reaction time, small size, and low cost. Also, the thermistor features a wide temperature range up to 125°C with excellent long-term stability. It is also quite robust and dust proof, making it suitable for use in industrial environments.

In conclusion, NKA103C1R10C thermistor is widely used in industrial products to sense, regulate and control the temperature change of the environment. It is highly reliable and stable, with a wide temperature range. It can be used with other devices such as operational amplifiers for temperature control or regulation.
