Through Hole Resistors are widely used in radio broadcasting, electronics related products, communication systems, and even medical equipment. They are commonly used in devices such as transistors, amplifiers, and integrated circuits. The use of Through Hole Resistors is versatile as it is possible to achieve a wide range of resistance values with resistors that can be installed in both surface mount and through hole packages. The RWR78S2R49FMB12 is a Through Hole Resistor that is popularly used in a variety of electronic devices.

The RWR78S2R49FMB12 Through Hole Resistor is composed of anodized aluminum, a resistive element, and a support. The resistance value is determined by the resistive element which can be a metal film, a carbon film, a metal oxide film, or a wirewound element. The characteristic of the resistor will be determined by the resistive element, as different resistive elements will provide different characteristics. Since the resistive element is encased in anodized aluminum, it is able to withstand high operating temperatures as well as electrical noise interference.

The RWR78S2R49FMB12 Through Hole Resistor is designed to provide a resistance range of 0.75 to 500Ω in increments of 0.75Ω, and a temperature coefficient of no more than 0.5%. This resistor is also rated for a maximum operating power dissipation of 0.5W and a rated peak pulse power of 4W. Due to its relatively low power rating, it is suitable for use as a pull-up or pull-down resistor. It can also be used as an output driver, or as an attenuator for over-driving sensitive signal-processing circuits.

The working principle of the RWR78S2R49FMB12 is quite simple. An electric current (I) is conducted through the resistor and dissipates power (P) as a combination of heat and an electric field. When the resistor is mounted to the circuit board, the electric current (I) is determined by a combination of Ohm’s law and network theory. The amount of heat generated by the resistor depends on the power rating of the resistor. The RWR78S2R49FMB12 is designed to dissipate 0.5W of power, and with a temperature coefficient of 0.5%, it can operate reliably in temperatures ranging from -55°C to +125°C.

In conclusion, the RWR78S2R49FMB12 Through Hole Resistor is an ideal component for use in a variety of electronic devices. Its low power rating, high temperature operation, and its precise resistance values make it suitable for use as a pull-up or pull-down resistor, an output driver, or as an attenuator. With its simple working principle, it is easy to see why the RWR78S2R49FMB12 is commonly used in various electronic applications.
