Through Hole Resistors

RWR71S1810FRRSL Application Field and Working Principle

Through hole resistors (or THRs) are resistors that are housed in cylinders, allowing leads to easily pass through the hollow center. This type of resistor is primarily designed for use in electronic circuits in order to regulate current flow and adjust signal levels. With regards to a specific electronic resistance model, specifically the RWR71S1810FRRSL, this device is typically used for signal conditioning applications, such as power supplies, waveform monitoring, and data acquisition.

Operation

THRs generally work by exploiting the relationship between electric current and voltage, which follows Ohm\'s Law. This states that the resistance of a circuit is the voltage divided by the current. In the case of a THR, the resistance value is determined by the material from which the resistor is composed. For the RWR71S1810FRRSL, this model is composed of a carbon film, meaning it has a comparatively fixed resistance.

The way in which a THR affects electrical signals is two-fold. Firstly, it acts as a voltage divider. This is because the voltage drop across the resistor is only proportional to the amount of current being supplied to the device. This essentially means that if the voltage remains unaltered and current rises, the voltage level across the resistor will rise accordingly. Thus, depending on the resistance value of the THR, the overall current entering a circuit can be reduced or increased accordingly.

The second way in which a THR affects electrical signals is via limiting current. It is well known that an increase in current will increase the voltage drop across a given resistance. If the current rises to an unsafe level, for example, the THR can act as a safety valve by preventing excess current from entering a circuit. This safety feature is important in many instances, since preventing electrical overloads is essential for system reliability.

Additional Facts

The RWR71S1810FRRSL THR is composed of a carbon film, allowing it to withstand a maximum of 1W of power at temperatures up to 175°C. It can be used for a variety of tasks, such as frequency control, power line protection, and protection from transient overloads. It is suitable for use in a variety of environments, from light industrial to harsh outdoor conditions.

The RWR71S1810FRRSL also complies with the Restriction of Hazardous Substances (RoHS) directive. This means that it does not contain any hazardous materials and is safe to use. Additionally, it is capable of withstanding significant levels of vibration and shock, making it an ideal choice for a variety of applications.

Conclusion

In conclusion, the RWR71S1810FRRSL THR is a reliable and robust resistor that can be used for a range of tasks, from frequency control to voltage and current regulation. Thanks to its carbon-based composition, it can be used in a variety of environments and provides significant levels of protection against overloads and transient events. It is also RoHS compliant, ensuring safe operation and compliance with relevant legal requirements.
