Through Hole Resistors

Through hole resistors, or THRs, are an essential component in electrical engineering, whether for large-scale industrial or commercial applications, or for small-scale hobbyist or domestic use. This type of resistor is designed to be mounted on a PCB (printed circuit board) via insertion through the holes of the board. The most common THR is the RSF200JR-52-680R, which is designed to withstand voltages of up to 6.8 V. The main function of a resistor is to create and control the flow of electricity by limiting the amount of current that can pass through it. This is essential for circuit and system stability, as too much current can cause overheating and even short circuits.

It is crucial to select the correct THR for the application, as incorrect sizing can reduce efficiency and cause issues. To correctly select the RSF200JR-52-680R, the application must not exceed a voltage of 6.8V. This component is suitable for use in AC circuits, as well as in DC circuits in both industrial and consumer equipment. Examples of equipment that can use RSF200JR-52-680R include computers, telecommunications equipment, LED lighting, electrical appliances, test and measurement equipment, and automotive electronics.

Working Principle

The primary principle of the THR is that it is a non-linear component, meaning its resistance value is not constant, and instead varies with respect to time and voltage. The current passing through a THR is proportional to the applied voltage, and this is known as Ohm’s Law. Depending on the application, the rate at which the current flow is controlled will vary. For example, in AC power supplies, a THR is used to limit the amount of current passing through a circuit, thus allowing the power supply to remain stable.

In addition, resistors can act as dampers in AC circuits. This is achieved by the use of the reactive component of the resistance, which acts as an absorption force for any capacitance or inductance that may be present in the circuit. This helps prevent high-frequency oscillations that may occur in the circuit, ensuring that the device remains stable and efficient.

As the RSF200JR-52-680R is a THR, it is thermally sensitive, and must not be exposed to voltage higher than 6.8V, as this can cause overheating. An important feature of this component is the ability to self-adjust its resistance value, meaning it can protect itself from potential overheating issues. This is due to the junction of the resistor material which will expand or contract in the presence of heat, thus changing its resistance value.

Conclusion

The RSF200JR-52-680R THR is a robust and reliable component that offers excellent protection for electronic systems with voltages up to 6.8V. It is suitable for a variety of industrial and consumer applications, and its self-adjusting feature ensures it can protect itself from potential overheating issues. Through hole resistors are an essential and integral part of any electrical circuit, and as such, it is important to select the suitable THR for the application. The RSF200JR-52-680R THR is an ideal component for both industrial and domestic applications, providing reliable and stable performance with adequate protection.
