Through Hole Resistors have been used in a variety of applications across industries due to their cost effectiveness and ease of installation. The RWR81N4220FRS70 is no exception. With its low tolerances and high operating temperature range, it provides solutions to all types of projects.

This resistor is constructed as a non-inductive, wire-wound, tantalum case with transistor-grade wire. The transistor-grade wire provides low noise and minimal temperature increases. Furthermore, the resistor has a temperature coefficient of resistance (TCR), which allows for higher precision and better accuracy in many applications. It also has an operating temperature range up to 175°C.

The RWR81N4220FRS70 has a wide range of applications. It is ideal for variable speed drives, heating and cooling applications, frequency converters, stepping motors, and power converters. It can also be used for other general purpose uses such as radio frequency (RF) filtering, running at high-voltages, and balancing current loads. With its high tolerance and temperature range, it can be used in a wide range of applications in a variety of industries.

The RWR81N4220FRS70 has a simple yet effective working principle. It includes a resistor element with two terminals, where one terminal is attached to the resistor surface and one terminal is left floating. When a potential difference is applied across the terminals, a current flows across the resistor element, creating a voltage drop. The amount of voltage drop depends on the resistance of the resistor element, which is why it is important to know the specific resistance of the resistor element when choosing the right resistor. The voltage drop is then used to regulate the current or the voltage in the circuit.

In conclusion, the RWR81N4220FRS70 through hole resistor is ideal for a variety of applications including variable speed drives, heating and cooling, frequency converters, stepping motors, and power converters. Its simple working principle consists of a resistor element with two terminals, where a potential difference is applied to create a voltage drop across the resistor element. This voltage drop is then used to regulate the current or the voltage in the circuit. With its low tolerances and high operating temperature range, this resistor provides solutions to all types of projects and is a cost-effective solution for many industries.
