Through Hole Resistors come in a variety of shapes, sizes, and types of resistors. The RWR81S40R0FRB12 is a Through Hole Resistor that is widely used in a variety of applications due to its reliable performance and quality. This article will discuss the application field and working principle of the RWR81S40R0FRB12.
The RWR81S40R0FRB12 is a Through Hole Resistor that is primarly used for current limiting, voltage zapping, thermal cycling, and over-current protection applications. The resistor offers superior performance in multiple applications such as motor control circuits, DC/DC converters, and synchronous rectifiers. It is also designed to be able to withstand extreme temperatures, which is why it is often employed in high-temperature automotive, aerospace, and military grade applications.
The RWR81S40R0FRB12 is constructed of a hi-Q metal-oxide film that is resistant to heat, pressure, and moisture due to its high dielectric strength. This feature ensures reliable performance and a long-life of the part. The resistor features an axial lead-form that further enhances its long-term durability and is ideal for through-hole resistors. The resistor also features a 0.46mm thick gold-plated end terminations that offer greater reliability and durability.
The working principle of the RWR81S40R0FRB12 is simple, yet effective. The resistor works by reducing the amount of current that passes through it, thereby limiting the amount of current flowing in the circuit and reducing the risk of damaging electrical components. This is done by introducing resistance into the circuit which limits the amount of current the resistor can handle. As the current passes through the resistor, heat is generated which is why the resistor is designed to be able to handle extreme temperatures.
The RWR81S40R0FRB12 Through Hole Resistor is a reliable and high-quality part that is widely used in a variety of applications. It offers superior performance and is designed to be able to withstand extreme temperatures. The resistor is constructed with a hi-Q metal-oxide film that is resistant to heat, pressure, and moisture, and features an axial lead-form that further enhances its long-term durability. The resistor works by limiting the amount of current passing through it, thereby reducing the risk of damaging electrical components. With its combination of reliable performance, quality, and resilience, the RWR81S40R0FRB12 Through Hole Resistor is a great choice for a variety of applications.
