Through Hole Resistors are a vital component of virtually any electrical system. The RL20S620GR36 is a particular type of through hole resistor that is designed to handle high-current applications. In this article, we will discuss the role of this type of resistor, along with its working principles and application fields.

What is a Through Hole Resistor?

A through hole resistor is an electronic component that limits the voltage and current flow in an electrical circuit. It is typically composed of a conductive material, such as a metal or an alloy, that is encased in an organic or inorganic coating. It is installed in a hole in the printed circuit board (PCB) when the resistor needs to remain connected with the PCB for a longer period of time. When the resistor is placed on the circuit board, it is said to be through-hole mounted.

RL20S620GR36 Features and Working Principle

The RL20S620GR36 is a through-hole resistor employed mainly in high-current applications. It is constructed using a thick-film resistor network that is integrate with an aluminum nitride substrate. The resistor includes three resistor elements; two fixed and one variable, which allows it to operate in different applications. The resistor can provide an adjustable resistance range of up to 36 Ohms. It also has an operating voltage rating of up to 60 VDC. It is rated for an operating temperature range of -40°C to 100°C, as well as a power dissipation of up to 2.5 Watts.

The working principle of the RL20S620GR36 is based on its three resistor elements. The first two resistor elements are fixed resistors with a specific resistance value. The third element is a variable resistor, which can be adjusted to provide different resistance values by turning a screw on the top of the RL20S620GR36. The three resistor elements are connected in a series-parallel network, allowing for the desired resistance value to be obtained by the user.
