Through hole resistors are components that helps to regulate the flow of alternating current (AC) or direct current (DC) in an electrical circuit. Among them, the ER5868RJT is a special case. This article will discuss its unique application fields and working principle.

ER5868RJT Application Field

An ER5868RJT is a non-inductive wire wound resistor that is designed for high power, high voltage applications. As such, it can especially be used in motor control and transportation systems that require high wattage ratings. Due to its high accuracy, low temperature drift and low noise output, it is used in high precision electronic and outdoor applications such as transformer control and marine-grade environments.

In addition to its high wattage rating, the ER5868RJT is also commonly used in high voltage circuit boards. It helps to regulate current in circuits that are subject to voltage spikes from environmental factors and components like relays. As such, the resistor greatly reduces the risk of damage to sensitive components.

ER5868RJT Working Principle

As a non-inductive wire wound resistor, the ER5868RJT relies on a unique form of electrical resistance. At its core, resistance is created when an electric current passes through a conductor. In this case, an oxide film is deposited on a wire, which in turn creates a thicker oxide film that resists electricity. This resistance is increased by the windings that are wound around the wire, thus resulting in a significant rise in voltage and current.

The ER5868RJT also employs a unique form of thermal protection. This feature ensures that the device will not be damaged when exposed to sudden currents or voltages. By employing a self-regulating temperature sensitive material, the resistor is able to protect itself from heat buildup as well. This is a significant advantage when it is used in outdoor settings, as the chances for a breakdown due to excessive heat is greatly reduced.

Conclusion

The ER5868RJT is an example of a through hole resistor that has been designed for high power, high voltage applications. As such, it is employed in motor control, transformer control, and marine-grade applications. Its high wattage rating, low temperature drift, and low noise output make it an ideal choice for a number of applications. It also features a unique thermal protection system that prevents heat buildup and damage from sudden increases in current or voltage.
