Through Hole Resistors are one of the earliest types of resistors available, and still remain a common choice for many applications. One variation of through hole resistors is the RL20S471GB14. Designed for various applications in a wide range of fields, the RL20S471GB14 offers excellent performance, low heat dissipation and thermal stability.

The primary purpose of the RL20S471GB14 is for voltage and current compensation in electronic circuits. It limits the voltage and current to acceptable levels and prevents damage to components. It is often used in power circuits, including high power heating element control, AC-DC power conversion, and lighting control. Additionally, it can be used in various timing circuits, such as short time pulse output, and press release latch/unlatch control.

The RL20S471GB14 acts as a non-inductive resistor, meaning that it has a low inductive impedance of 15Ω at a frequency of 20–40MHz. This allows it to function properly even when operating at very high frequencies, providing excellent performance for its intended application fields.

The RL20S471GB14 also features a low resistance value of 4.71Ω and a power rating of 10W. This allows it to be utilized in situations where it needs to dissipate a significant amount of power. The construction of the RL20S471GB14 is also designed for practical usability. It can be soldered to PCB boards, as well as provided with screw hole threads for safe and easy mounting.

The working principle of the RL20S471GB14 is simple yet effective. It is composed of a resistive element encased in an insulator, such as plastic or potting compound. When a current is passed through the resistive element, it generates a voltage drop across the resistor, limiting further current flowing through it. This will also reduce the system voltage to an acceptable level, allowing the circuit to operate correctly.

In conclusion, the RL20S471GB14 is an extremely versatile through hole resistor, offering excellent performance and durability for a wide range of applications. Its low resistance value, power rating and non-inductive construction make it a great choice for many applications, including power and timing circuits. Its simple working principle relies on the resistive element to dissipate an appropriate level of heat and voltage, allowing the circuit to function correctly.
