Through hole resistors are a type of resistor on which the body extends through a hole in the printed circuit board, the back end of the resistor then connected to a piece of wire, thus forming a complete electrical circuit. The SQM300JB-39K is a part of the through hole resistors type, and it is an axial leaded, commercial grade, fixed-value wire-ended resistor.

The SQM300JB-39K through hole resistors are available in five different values with resistance ratings from 10 ohms to 4.7M Ohms. The working principle of this type of resistor is quite simple. An electrical current passes through the body of the resistor, and a voltage is developed proportional to the resistance of the resistor. The voltage is equal to the current times the resistance.

The SQM300JB-39K through hole resistors are mainly used in applications where resistance values are stable and predictable. Some of the most common applications for which this type of resistor is suitable include signal conditioning, circuit protection, voltage reference, and voltage divider circuits. For example, the SQM300JB-39K can be used as a voltage divider in order to create a different voltage level in a circuit, or to provide a reference voltage for a voltage regulator circuit.

Besides their use in these various applications, through hole resistors can also be used for other purposes. They can be used for matching to other components, such as communications equipment or other resistors, in order to help improve signal integrity and prevent noise. In addition, they can be used to help limit the current when one part of the circuit is drawing more current than it should, thus preventing damage to the component.

Finally, through hole resistors can also be used in safety circuits, such as airbags or seat belts, in order to limit the current in those circuits and ensure that they operate safety. With their wide range of applications, through hole resistors have become an increasingly popular method for providing reliable and predictable resistance values in various electrical and electronic circuits.
