Through Hole Resistors have been utilized in a variety of applications due to their robust construction, reliable performance, capability to perform in hostile environments, and their extraordinary ability to dissipate large quantities of power. The 20J5R0 is a popular Through Hole Resistor that is designed to function in both AC and DC circuits and to withstand temperatures up to 250°C. It is available in both Military grade and commercial grade versions with endurance levels defined by the type of resistor that is used.

20J5R0 Application Field

The 20J5R0 Through Hole Resistor is primarily used in applications that require either high power density, low thermal resistance, or both. Its design allows for a high power rating combined with low thermal resistance, in order to both withstand and dissipate large loads. The 20J5R0 is suitable for applications with both high current and high voltage, such as power supplies, high current switches, and high voltage inverters. Additionally, the 20J5R0 is also used in applications that involve high speed circuitry, such as pulse width modulators, converters, and motor drives.

20J5R0 Working Principle

The 20J5R0 Through Hole Resistor consists of four major components: a ceramic body, a resistor element, a ceramic isolator, and an epoxy cover. The ceramic body provides mechanical and thermal stability to the resistor elements and isolator while the resistor element provides resistance to the flow of current. The ceramic isolator provides electrical isolation between the resistor element and the ceramic body and helps to dissipate the heat generated by the resistor. Finally, the epoxy cover acts as a dielectric barrier between the resistor element and the external environment. When a current passes through the resistor element, the resistor element produces a small amount of resistance due to the energy created by the electrical current. This resistance is then dissipated as heat through the ceramic isolator.

The 20J5R0 Through Hole Resistor is designed to be used in both AC and DC circuits and can withstand temperatures up to 250°C. It is available in both military grade and commercial grade versions, with endurance levels defined by the type of resistor that is used. The 20J5R0 has been designed with a high power rating combined with a low thermal resistance which makes it suitable for a wide range of demanding applications.
