Through Hole Resistors are essential components in circuits, and RC12KB130K is one type of them. In this section we will expound the application field and working principle of RC12KB130K.

First, application field. RC12KB130K is a power tool resistor, designed for all kinds of industrial control equipments along with other components. It connects in series with the load bearing device and usually operates under high temperature and high current scenarios. With excellent performance for frequency applications, RC12KB130K also applies to computer, telecommunication, instrument and other small electronic devices.

Now, we can look at the working principle of RC12KB130K. Its internal structure includes pure nickel-chrome heating wire, ceramic insulator and aluminium ring shape cap. Supposed the current passing through the resistor is I and the total opposition is equal to the resistance R, the main function of RC12KB130K is to limit the current running in certain range. According to general Ohm\'s law, the voltage across the resistor should be RV.

That is to say, when I flows through RC12KB130K, electric power P consumed can be calculated asPR=VI=R·I2. It is known that as the resistance increases, the power dissipation of RC12KB130K also increases. Hence its permitted power dissipation should not exceed the tolerance to avoid thermal runaway or permanent damage.

In addition, we also need to mention temperature coefficient and power tolerance of RC12KB130K. Temperature coefficient is used to evaluate the changes in resistance when the temperature alters while power tolerance is the highest power the resistor can bear. When selecting RC12KB130K, make sure to choose components with proper temperature coefficient and power tolerance value.

To summarize, RC12KB130K is a type of power tool resistor applicable for industrial control equipments, computers and other small electronic devices. The working principle is based on Ohm\'s laws, where the total opposition is equal to the resistance and voltage across the resistor should be equal to resistance multiplied by current. Moreover, pay attention to the temperature coefficient and power tolerance before purchasing RC12KB130K.
