Through-hole resistors, sometimes referred to as leaded resistors, are the classic style of resistors, distinct for their cylindrical components with leads protruding from each end. The main features of this type of resistor are its durability, good thermal characteristics, good electrical characteristics, and good solderability. In the majority of cases, through-hole resistors are constructed from ceramic coated metal film for greater stability and high power rating. As these resistors are available in a wide range of sizes and categories, they are today\'s most popular type of resistor, and particularly suitable for higher power applications. A through hole resistor used for these applications is the RL20S123JRSL.

The RL20S123JRSL is a leaded resistor with a 1 watt power rating. It has a low profile (6.8mm) body and is low cost compared to other types of resistors. It features a flameproof construction, a wide operating temperature range between -55°C and +125°C and a narrow tolerance of +/-3%. Additionally, this type of resistor is also capable of withstanding up to 2500 volts of surge voltage.

The RL20S123JRSL resistor typically operates as either a positive voltage or current regulator, providing a nearly linear temperature coefficient of resistance over a wide range of temperatures. It also has a uniform performance over a wide range of frequencies and is suitable for a wide range of applications, such as audio crossover networks, RF attenuators, power supplies, and RF communication systems. Additionally, this leaded resistor is also resistant to noise, moisture, and vibration, making it an ideal choice for high reliability and high temperature applications.

The working principle of the through-hole RL20S123JRSL resistor is based on the Ohm’s law, which states that the current through a resistor is proportional to the voltage across it. The resistor itself is composed of a round piece of ceramic-coated metal film with two leads attached. When a voltage is applied across the leads, a current will pass through the resistor and it will produce heat. This heat is dissipated by the ceramic and metal components, and is monitored by a thermistor for safety.

The RL20S123JRSL is a highly reliable, cost-effective resistive solution for many applications, as its performance is highly reliable over a wide temperature range. Its a stable device with a resistance value that remains more or less the same even after long periods of operation. This makes it suitable for a variety of audio, video, and instrumentation applications. Furthermore, its strong mechanical and environmental characteristics ensure a long lifetime, making it an ideal choice for projects that require a durable, reliable resistor solution.
