Through Hole Resistors are a common, fundamental part of any electronic system, providing components with an electrical resistance. This is essential for regulating the flow of current and protecting sensitive circuits from electrical overloading.

RWR80SR267FRS73 is a Through Hole Resistor, part of the RWR80 series from the manufacturer EPCOS. This series of resistors, known as "Power" MELFs, are made of leaded axial components in a ceramic tube, and are suitable for extended range for power rating in board mounted applications.

The RWR80SR267FRS73 model has been designed as a Through Hole Resistor to serve a range of purposes. Its features – such as its small physical size and variety of height and construction options – make it suitable for a range of circuit designs. Additionally, it features a power rating of 0.5/1/2/3 Watts and a minimum resistance of 0.1 ohms.

RWR80SR267FRS73\'s application field extends further than just circuit protection as mentioned above. It is also used in power supply control, overvoltage protection, negative temperature coefficient (NTC) thermistors, signal filters, and other circuit applications.

The working principle of RWR80SR267FRS73 is simple to understand. It contains an internal resistor – often made of manganin, a copper-manganese-nickel alloy – between two terminals. This produces a predictable resistance value, as specified by EPCOS. When current flows through the resistor, Joule heating produces heat, which is dissipated through the ceramic tube.

The two terminals can be connected to different points in a circuit, limiting the flow of electrical current through the resulting pathway. This can be used for simple purposes such as limiting the current flow within a circuit and protecting sensitive components. Or it can be used for more advanced purposes, such as voltage level conversion, signal filtering, or thermistor temperature sensing.

In conclusion, RWR80SR267FRS73 is a versatile Through Hole Resistor from the EPCOS series. It boasts a power rating of 0.5/1/2/3 Watts and a minimum resistance of 0.1 ohms, making it suitable for a variety of applications in circuit designs. It works by making use of its internal resistor to limit the flow of current, protecting the components and circuits from potential overloads.
