Through Hole Resistors

A through hole resistor (SQP700JB-1R5) is a fixed electrical component that has a known resistance value and can be used to regulate the electric current in an electrical circuit. This type of resistor is through-hole mounted, which means it is placed on the circuit board, with the two leads going through holes in the board and soldered in place. The resistance value of the resistor is printed or stamped on its body and then the resistor is heat-shrunk to protect it from damage.

Application Field

Through hole resistors play an important role in many electronics applications, ranging from simple electronic control circuits to sophisticated telecommunications systems. They are especially useful in high power applications, as they can dissipate a large amount of heat generated by the current passing through them. The value of a resistor is usually indicated in ohms, which is the unit of resistance. By using these resistors, the current flowing through a circuit can be varied by the user, depending on their particular needs.

Working Principle

The working principle of the through hole resistor is simple. A resistor is simply a conductor with a specific resistance across its length. The amount of current passing through it is inversely proportional to the resistance amount. This means that if a resistor has a higher resistance, the same amount of current will flow through it at a lower voltage. As a result, the amount of voltage and current in an electrical circuit can be regulated accurately by using a through hole resistor.

In addition, through hole resistors can be used to limit the amount of current flowing through a circuit to prevent circuit damage. The most commonly used type of through hole resistors are carbon composition, carbon film, metal film, wire wound, and surface mount resistors. They are available in a variety of shapes and sizes, so they can be used for different applications.

Conclusion

The through hole resistor is an essential component of any circuit and has a wide range of applications. It is easy to use, and with its wide range of resistance values and sizes, it can be used to regulate the current in any electrical circuit. When selecting a resistor, it is important to consider the required value, size, and the environment in which the resistor will be used to ensure it is suitable for the intended application. SQP700JB-1R5 is a reliable through hole resistor and is commonly used in electronics applications due to its durability, affordability, and resistance accuracy.
