Working Principle

The working principle of the SQM10AJB-680R is relatively simple. It is composed of two or more resistors connected in series or parallel. When an electrical current passes through the resistor, it creates a voltage drop across the resistor. This voltage drop is proportional to the amount of current flowing through the resistor. The total resistance of the resistor is equal to the sum of the individual resistors.

The SQM10AJB-680R also has a temperature coefficient. This means that the resistance of the resistor will change depending on the temperature. The larger the temperature coefficient, the larger the change in resistance for a given change in temperature. This is useful for applications where the resistor needs to remain at a constant resistance over a wide range of temperatures.
