Through hole resistors like RWR71S2491FSB12 exploit the principle of electrical resistance in order to have a wide range of usage in multiple industrial applications. By dissipating electrical energy, such tools allow for the manipulation of energy needs in the system, for example to limit the amplitudes of signals, provide current pulses, or create precise voltage values.

A resistor is defined by two important values, its resistance and its maximum dissipation. Resistance usually measured in ohms while power, in watts, is the maximum amount of power that can dissipate without damage due to overheating. In turn, this means that power represents the electrical energy that will be converted into heat energy.

The resistor with reference number RWR71S2491FSB12 is a through-hole resistor, meaning that it houses two metallic supports with permanent connections that make it possible to pass the electrical current between them. These supports are usually made of metal, such as stainless steel or zinc-plated steel, and are coated with a dielectric tea seal to protect the element.

The references that make up the RWR71S2491FSB12 resistor are divided into three parts. The RWR71 is the resistor Reference, followed by the S2491 indicating that it is a Through Hole resistor and the FSB12 number that specifies the size and type of the element. This allows us to infer that it is a Through Hole resistor of a size 12 with a Forsheda-Bergqvist type of terminals.

Although the working principle of RWR71S2491FSB12 and other resistors of this type remain the same, the many variations in size, power, and temperature ranges can lead to a different range of operating conditions in which to use them. To this end, surface and through-hole resistors designed and manufactured for general electronics applications comply with many standards such as RoHS, Reach, EMC, and military standards.

For example, in industrial fields such as automotive, aerospace, computing, telecommunications and medical technology, high performance and reliability are often required from resistors. Such components must, for example, be able to withstand extreme temperatures and elevated humidity fluctuations. In such cases, Through Hole type resistors are more suitable for long-term storage and operation and have the added benefits of easy mounting, replacement, and packaging.

The four main applications of Through Hole resistors, such as RWR71S2491FSB12, are: series wiring, parallel wiring, voltage divider, and current limiter. Series wiring is commonly used to increase the resistance of a circuit. For example, to increase the current-carrying capacity of a circuit, multiple resistance values can be connected in series, thus further raising the resistance. Parallel wiring is where multiple resistors are joined together with no intersecting points between the two wires. This type of wiring is often used to reduce the total resistance in a circuit. Voltage dividers are utilized to distribute power among various components connected in series. Finally, current limiting is used to restrict the voltage or amount of current in a circuit.

Therefore, Through Hole resistors like the RWR71S2491FSB12 provide a range of practical solutions in the electronics industry. The resistance values allow for electrical energy to be converted into heat energy, allowing for precision use in various applications. Whether working in the automotive, aerospace, medical or any other field of electronics industry, there is always a need for reliable components, such as the RWR71S2491FSB12. With its high-performance and flexibility, these elements will remain a beneficial part of the industry for years to come.
