Through hole resistors are used to provide electronic circuits with the ability to measure current and voltage, as well as to limit the flow of current to protect components. The RL20S181GRSL series is a type of through hole resistor that is commonplace in many applications due to its compact size, high power handling capability, and wide operating temperature range. This article seeks to examine the applications and working principles of RL20S181GRSL through hole resistors.

Applications of the RL20S181GRSL

The RL20S181GRSL series is a type of through hole resistor that is used in many different applications. It is a low resistance, high power handling resistor that is very versatile in both commercial and industrial applications. It can be used as a voltage divider or as part of a voltage regulator circuit. It can also be used to measure current up to 4 Amps through its small size. The RL20S181GRSL can operate from -40°C to +135°C without affecting its performance, making it an ideal choice for applications in harsh environments.

Another application of the RL20S181GRSL is in automotive electronics. Since the resistor can handle high power and operate in extreme temperatures, it can be used in vehicles to control or limit the amount of current sent to various components. This allows vehicle systems to function properly without the risk of damage from too much current. The RL20S181GRSL is also used in automotive audio systems, where it is used in the amplifier’s volume control. This ensures that the user gets the desired level of output without causing any damage to the system.

The RL20S181GRSL can also be used as a precision current source in many instruments. It can be used to provide a controlled current, which is ideal for calibrating meters, sensors, and other instruments. Furthermore, the RL20S181GRSL can be used for power regulation in high voltage power supply systems. It is also used in solar panel systems to regulate and limit the amount of current supplied to the panels.

Working Principle of the RL20S181GRSL

The RL20S181GRSL series resistor is a type of resistor made up of two electrically conductive metal alloy stripes. These stripes are connected to two ends of a coil of wire. When a current is applied to the resistor, the coil of wire creates a magnetic field, which causes the metal alloy stripes to move towards each other, thus increasing the resistance. This movement of the metal alloy stripes is what makes the RL20S181GRSL a variable resistor.

The RL20S181GRSL can measure current up to 4 Amps and can be used for both AC and DC applications. When used in AC applications, the resistor can measure both the peaks and troughs of the current waveform. The RL20S181GRSL can also be used as a precision current source to provide a controlled current for calibrating meters and other instruments.

The RL20S181GRSL series through hole resistor is an ideal choice for applications that require a high power handling capability, wide operating temperature range, and a small size. It can be used in automotive, industrial, and commercial applications to provide regulated current, measure voltage and current, limit current, and calibrate instruments. This makes it a versatile and reliable resistor for many different types of applications.
