Through Hole Resistors are components that restrict a flow of current. They are used in a variety of electronic circuits for various purposes, including providing feedback in feedback circuits, setting reference voltages, or providing current limiting. The specific model under consideration in this article is the ERG-2SJ203. This Through Hole Resistor comes in two sizes, the axial leaded ERG, and the smaller, wrap-around case ERG-F.

The primary application of the ERG-2SJ203 is in power applications such as variable speed drives, instrumentation and current limiting. The ERG-2SJ203 was designed to provide current limiting and an efficient electricity consumption experience. The ERG-2SJ203 is capable of both current limiting and voltage regulating, a combination that makes it a practical option for applications that require variable current settings.

The working principle of the ERG-2SJ203 is based on the temperature coefficient. This component uses the resistor thermistor element to sense the current and increases the resistance in the presence of a decrease in the voltage. This ensures that the desired current setpoint is maintained. The thermistor element is also used to sense the change in temperature, and to adjust the voltage accordingly. This ensures that the temperature of the resistor does not exceed the maximum recommended values.

The ERG-2SJ203 is typically mounted on a printed circuit board. The board features two contact holes that allow for quick and easy installation. The two contact holes carry the current to the preset resistors, where the current is converted to a ratio based on the resistor’s formulation. The ratio is then multiplied by the amplitude of the voltage to calculate the current output. This process ensures that the current is regulated at the desired levels.

Advantages of using the ERG-2SJ203 include the fact that it is relatively small in size and lightweight in design, making it easy to install and use in tight spaces. It is also highly reliable and provides accurate readings. As well, it offers a wide temperature range of operation and can handle up to eight amps. The accuracy of the current readings is also ensured by a high-performance temperature coefficient.

In conclusion, the ERG-2SJ203 is a Through Hole Resistor that is primarily used in power applications such as variable speed drives, instrumentation, and current limiting. It offers a variety of features, including a wide temperature range of operation, accuracy, and reliability. Its small size and lightweight design make it easy to install and its temperature coefficient ensures accurate current readings. This component is therefore an appealing option for those looking to add a reliable and efficient current limiting device to their electronic circuit designs.
