Through-hole resistors are very common passive components that can be found everywhere in electric and electronic circuits. The RWR80SR340FRS73 resistor is just one of the many resistors on the market. It is used in various applications and is widely available. In this article, an overview of the application field and working principle of the RWR80SR340FRS73 resistor will be provided.

Application field

The RWR80SR340FRS73 is designed for high-current applications with power ratings ranging from 24 to 3 W. It is suitable for use as an automatic control circuit, a current sensor, and a temperature limiter. Due to its wide resistance range and high current rating, it is often used in commercial, industrial, and military industries. In commercial applications, it is widely used to regulate current in industrial motors, DC-DC converters and air conditioners. It can be found in circuits such as audio amplifiers, automotive engines, and home entertainment systems. In military applications, this resistor is used in control systems of all kinds.

Working principle

The RWR80SR340FRS73 is based on a thick-film metal oxide ceramic resistor mounted in an enclosed tin box. The resistor consists of a sheet of molybdenum disilicide coated with a layer of thick-film metal oxide ceramic on top. The resistor is soldered onto a printed circuit board and is then sealed in a metal box with a thermal plastic compound. The resistor is designed to dissipate heat which is generated from the resistance material. When current is applied to the resistor, a small voltage is generated which is proportional to the resistance valuemeasured in Ohms.

The RWR80SR340FRS73 has a tolerance of +5% or -5%, which means that the actual resistance value will deviate by up to 5% from the nominal value. This tolerance is due to the fact that the resistor is made up of a molybdenum disilicide-coated layer of thick-film metal oxide ceramic, which varies in its resistance value slightly and thus leads to the tolerance range of +5% or -5%.

The RWR80SR340FRS73 has a wide variety of applications due to its wide resistance range and high current rating, making it a popular component in many commercial, industrial, and military industries. Its working principle is based on a thick-film metal oxide ceramic and a molybdenum disilicide-coated layer of thick-film metal oxide ceramic, which together create a high-quality resistance material. With its tolerance of +5% and -5%, the RWR80SR340FRS73 is an ideal choice for many applications.
