Through Hole Resistors are widely used in many industries because of their ability to energize circuits. The ERG-3SJ473A, commonly referred to as a 470 ohm 3 watt through hole resistor, is one such device that is utilized for many different applications including power supplies, portable radios, amplifier circuits, battery chargers, and voltage regulation. This resistor is designed for use in hostile environments due to its nonvolatile design. It also has a high insulation resistance which prevents buildup of static electricity. This component is designed for moderate to high AC power, and has a wide operating temperature range with a power rating of 3 watts at 70°C.

The ERG-3SJ473A works by the electrical conduction of electrons through it. This conduction creates resistance which can be used to regulate current for specific circuits. These through hole resistors have a variable resistance which can be changed depending on the environment or application. This is done by adjusting the length of the resistive element and the size of the hole in the body which is often referred to as the body size. The accuracy of these resistors is determined by their precision and tolerance. The precision is the amount of variation of the resistor’s resistance, while the tolerance is the amount allowed within the resistor’s resistance range.

The ERG-3SJ473A through hole resistors are available in several different package types to best meet the performance requirements of a particular application. The packaging can be determined by the voltage and current levels which are needed. These packages include axial, radial, and surface mount. The axial is the most common configuration as it has a lead that is exposed on both ends, and is used for low current applications. The radial package is a two-terminal device with its leads bent outward on either side, suitable for higher power applications. The surface mount package is the smallest of the three, with SMD (Surface Mount Device) construction.

In addition to the packages available, these through hole resistors come in different forms for versatile applications. These forms include axial-leaded, wirewound, and film-type units. The axial leaded resistor is mounted through the use of its leads and is the most common form. The wirewound units have wound wires on a ceramic core which improves the power rating and their heat dissipation. The film-type units have a carbon film or metal-oxide film which is used to create a high insulation resistance and higher tolerance.

The ERG-3SJ473A can be used in many different applications due to its high voltage and current ratings. It is a popular choice for many industries as it provides stable and reliable performance in hostile environments. This through hole resistor is available in different packages and sizes depending on the application, and is available in axial, radial, and surface mount forms. It has a wide operating temperature range with a power rating of 3 watts at 70°C, and has a good tolerance and precision rating. All of these features make this through hole resistor an ideal choice for many applications and industries.
