Introduction

RWR78S1240FRB12 is an through hole resistor manufactured by Rohm Electronics. This type of resistors are widely used in the industrial, commercial and consumer applications. The resistor features long life, high thermal and overload performance, as well as low inductance and high reliability. It is also RoHS compliant and meets UL Standards.

Application Field

Through hole resistors are mainly used in applications where a wiring solution is preferred over soldering. These resistors are used in circuit board and panel wiring as components that limit current flow. They can also be used in motors, automotive, instrumentation and other equipment. Through hole resistors are mainly used in industries in order to protect electronic equipment from damage caused by excessive current. In the automotive industry, through hole resistors are used in applications where high power and high temperature environments are common.

Working Principle

Through hole resistors work on the principle of ohm\'s law. When current passes through the resistor, it is impeded and an electrical energy is converted into heat energy. This heat energy is dissipated through the copper plating of the resistor and the heat sink. The resistance of the resistor is determined by the resistance material that is used. Typically, manganese-coated copper wires are used, but other materials such as polysilicon and titanium can also be used. The resistance material is coated with nickel or silver to increase its durability.

Advantages of Through Hole Resistors

Through hole resistors have several advantages that make them preferable to other types of resistors. Firstly, through hole resistors can be easily replaced or changed, allowing for easy maintenance. Furthermore, through hole resistors can be mounted on circuit boards without soldering, which makes them much easier to work with. Finally, through hole resistors are more reliable due to their robust construction.

Conclusion

RWR78S1240FRB12is an through hole resistor manufactured by Rohm Electronics. It is mainly used in industrial, commercial and consumer applications where a wiring solution is preferred over soldering. The resistance of the resistor is determined by the resistance material that is used, and the resistor is coated with nickel or silver in order to increase its durability.
