Through Hole Resistors are an integral component to many electrical designs. RL20S123GR36 is a typical two-terminal from the resistor family, its application field and working principle is elaborated in this article.

Application Field of RL20S123GR36

RL20S123GR36 belongs to the through-hole resistor family, and with a 2W rating it is suitable for a broad range of applications. Common use cases include:

• Circuit boards in audio components, such as loudspeakers and amplifiers.
• Capacitors and other semiconductors in high power computer systems.
• Relays in high-voltage home appliances.
• Battery voltage equalization in mobile phone devices.
• As a voltage regulator for high-powered LED lights.

The versatility of the RL20S123GR36 is due to its ability to withstand high power loss and voltage flickers. This is why it is widely used in high voltage element circuits.

Working Principle of RL20S123GR36

RL20S123GR36 is a type of carbon film resistor, which works by creating a resistance to the flow of electricity. The electrical current enters one end of the resistor and is reduced in intensity as it passes along the length of the resistor. This resistance is created by a specific type of material (carbon film) which has inherent properties that make it difficult for electricity to pass through it.

Unlike other types of resistors, the RL20S123GR36 incorporates a pair of lead wires, one for each end of the resistor. The leads are insulated from each other by an insulating layer, and the resistance of the resistor is determined by the thickness of the insulating layer. The longer the lead wires, the higher the resistance, and vice versa.

The RL20S123GR36 is also known as a fixed resistor, since its resistance is not adjustable once it has been designed. To alter the amount of resistance a variable resistor would be required, such as those found in potentiometers.

Conclusion

The RL20S123GR36 is a two-terminal resistor used widely in high voltage applications. Its design incorporates a pair of lead wires that are separated by an insulating layer, where the resistance of the resistor is determined. It is non-adjustable resistor due to its fixed resistance, which makes it useful in a wide range of applications.
