Resistors are fundamental electrical components used to control the flow of electrical current through electrical circuits. They come in several types and sizes and serve myriad purposes when it comes to controlling current. One resistor type is the through-hole resistor. A through-hole resistor, as the name implies, is a resistor that has leads extending through its body, and this type of resistor includes the RWR81S8660FRB12 series.

Generally, the RWR81S8660FRB12 series are categorized as Surface Mount Device (SMD) resistors. These devices measure just 1.15mm x 0.6mm and they feature a resistor body with two leads. The main applications of RWR81S8660FRB12 series are in niche industrial and automotive electrical systems, such as those used in solar energy control, automotive alternator control, and variable frequency motor control. Additionally, RWR81S8660FRB12 resistors are capable of providing good insulation performance and heat dissipation capabilities without additional cooling devices.

The RWR81S8660FRB12 series resistor schematic symbol is shown in the figure below.

Each RWR81S8660FRB12 through-hole resistor consists of a two-terminal chip which is encased in a thermally conductive, hermetically sealed package. The two terminals, known as the emitter and collector, create a resistive path for controlling the current flow in the circuit. In addition, the package includes connected elements such as a heat sink, a capacitive junction, and small-signal transistors.

The working principle of a through-hole resistor of the RWR81S8660FRB12 series is fairly simple. When a current (Ie) passes through the emitter and collector of the device, a resistor value (R) is created which limits the amount of current that can flow through the circuit. The resistor value is predetermined in the chip and is usually made up of a combination of carbon resistors, ferrite beads, and semiconductor components. The resistor value is generally in the range of 1KΩ to 56KΩ.

The electrical characteristics of the RWR81S8660FRB12 series resistors are typically defined in terms of ohms, wattage, voltage drop and current rating. Temperature coefficient, power dissipation, and voltage rate are also important features to consider when selecting these resistors for a particular application. The operating range of these through-hole resistors can be anywhere from -55°C to +85°C.

In conclusion, the RWR81S8660FRB12 through hole resistors to provide reliable, cost effective solutions for applications such as solar energy control, automotive alternator control, and variable frequency motor control. It is important to consider the design criteria and electrical characteristics of these resistors and to select them carefully for the best performance.
