Through Hole Resistors are one of the many passive components used in circuits. A resistor acts as a barrier to resist the flow of electrons, and when paired with other components, they can be used to control the speed, amount, and direction of the current. The ER7482RJT is one type of through hole resistor, and its applications and working principles are discussed in this article.

ER7482RJT Application Field

The ER7482RJT is a through hole resistor that is commonly used in electronics, automotive, and aerospace applications. This resistor is designed to be used as a power supply current limiter, and it is also commonly used as an active current limiting device. Its resistance is fixed, meaning it can be used to prevent overvoltage in sensitive components or circuits. It is also low in capacitance, making it suitable for high speed applications. Because of its wide operating temperature range, it can be used in extreme environments, making it a popular choice for automotive, aerospace, and other industrial applications.

ER7482RJT Working Principle

The ER7482RJT is a voltage-controlled resistor, meaning its resistance is determined by the applied voltage. It has a high amount of stability, meaning it maintains its resistance within a very small range, even under changes in temperature. The resistor is constructed with two metal plates, which are connected by lead wires and mounted in a housing. Between the two plates is a special ceramic material, which increases the device\'s electrical isolation, meaning it can be used to keep separate parts of the circuit from interfering with each other.

The ER7482RJT works by passing an electric current through the ceramic material between the two metal plates, causing the resistance of the ceramic material to decrease. This decrease in resistance causes the voltage at the resistor terminals to drop. By controlling the amount of current through the ceramic material, the ER7482RJT can be used to limit the voltage at the circuit nodes. For example, in a circuit with high voltage, the ER7482RJT can be used as a current limiting device, protecting the circuit against excessive voltage.

The ER7482RJT is a low-cost and highly reliable device, making it a popular choice for many applications. Its wide temperature range, low capacitance, and high stability make it suitable for high speed applications, while its current limiting capabilities protect sensitive circuits from damage. With its wide range of applications, the ER7482RJT is a popular and cost-effective choice for many through hole resistor applications.
