Chassis mount resistors are components designed to provide electrical resistance in an electronic circuit. The RER70F6980RC02 is a type of chassis mount resistor used in many applications. In this article, we\'ll take a look at the RER70F6980RC02\'s application field and working principle.

Application Field

The RER70F6980RC02 is a 0.47ohm precision resistor with a Tolerance of 1%. It is a popular choice for applications where a stable resistance is required over wide temperature and power variations. With its specialized design, the resistor is able to handle a wide range of voltages, frequencies, and currents. Its low residual inductance and thermal resistance make it ideal for applications such as automotive, industrial, and military.

The resistor is also used in board-level applications, such as power supplies, signal processing, and communication networks. It is commonly found in RF amplifiers and filters, as well as in circuits requiring high-accuracy resistors with tight tolerance and low temperature coefficient.

Working Principle

The RER70F6980RC02 operates based on the principle of electrical resistance. When current passes through the resistor, a small voltage drop is produced. This voltage drop is determined by the resistor\'s resistance. Thus, by controlling the amount of current passing through the resistor, the resulting voltage can be adjusted.

In addition to the voltage drop, the resistor also reduces current flow through the circuit, providing a degree of protection against overcurrent. The resistor also dissipates energy as heat, which can affect the performance of the circuit. For this reason, it is important to choose a resistor with an appropriate wattage rating for the application.

The resistance of the RER70F6980RC02 is determined by its construction and composition. It consists of a metal film bonded to the surface of an insulating substrate, such as alumina or silicone glass. The layer of metal film is composed of materials such as nickel-chromium, nickel-iron, and manganese-nickel alloy, which determine the resistor\'s resistance value.

Conclusion

The RER70F6980RC02 is a precision resistor component that offers a stable resistance over wide temperature and power variations. Its low residual inductance and thermal resistance make it ideal for automotive, industrial, and military applications. Its resistance is determined by the composition of its metal film, and it offers protection against overcurrent by reducing current flow. With its specialized design, the resistor is capable of handling a wide range of voltages, frequencies, and currents.
