Through hole resistors are typically used when larger components are required. This is because they have a hole in the body of the component that allows for larger, thicker pieces to fit through, such as wires, when build the circuit boards. The RWR81S7R68FSB12 type of through hole resistor is one of the most common and versatile resistors. It can be used for a variety of applications including amplifier circuits, bias circuits, voltage divider circuits and many more.
The RWR81S7R68FSB12 is commonly referred to by its three-digit code, 817. This code describes the package size of the resistor, the maximum wattage it can handle, and its maximum current rating respectively. The 817 package is a large, cylindrical device that provides superior heat dissipation when compared to the smaller 2-digit coded surface mount versions.
The working principle of the RWR81S7R68FSB12 through hole resistor is based on Ohm\'s Law. According to Ohm\'s law, current can be prevented from flowing through a circuit by applying a specific resistance. The amount of resistance, or impedance, is a function of the material used in the resistor, the size of the resistor, the shape, and the environmental conditions. The RWR81S7R68FSB12 uses a carbon composition material to achieve a resistance of 500 ohms at 25 degrees Celsius. This resistance will vary slightly depending on the environment and external conditions.
The application fields of RWR81S7R68FSB12 through hole resistors are vast and varied. These devices are commonly used in amplifier circuits, bias circuits, voltage divider circuits and as protection against overvoltage surges. Because of the robust design and large packaging size, this type of through hole resistor is also well suited for use in high temperature and high voltage applications. Additionally, they are commonly used in medical and industrial applications where reliable performance over time is critical.
The RWR81S7R68FSB12 through hole resistor has proven to be an invaluable addition to electrical systems in a wide variety of settings. Its robust design and large package sizes make it a great choice for high power applications, and its reliable performance makes it a suitable choice for medical and industrial applications. Knowing the application field and working principle of this resistor is essential to ensure that its use is as efficient and effective as possible.
