Through-hole resistors are passive electronic components, and one of the most common resistor types is the ERG-2SJ121A. They are generally cylindrical and fit perfectly into through-hole locations on a printed circuit board. Through-hole resistors are composed of two metal leads that extend from opposite sides of the resistor body, with paint or ink printed on the top to indicate their value and tolerance. Their huge advantage is that they are available with a variety of values and power ratings, from a few ohms to several megohms.
ERG-2SJ121A application field and working principle
First, the application field of ERG-2SJ121A is extremely wide and includes electronics, automotive, military, and aerospace industries. ERG-2SJ121A is most commonly used in analog circuits, current and voltage regulation, Voltage Dividers, Power Supply Circuits, Radio Frequency (RF) and High-Frequency designs, and Decoupling.
Second, the working principle of ERG-2SJ121A is based on the semiconductor resistance-controlling property. Through-hole resistors are manufactured from high-resistance and heat-resistant materials such as carbon, metal oxide, and film. The material creates a fixed resistance value that can be adjusted by varying the thickness of the material or lengthening the length of the resistor body. During operation, electrons flow through the resistor and the material forms an electrical barrier, which is responsible for the resistance created. This phenomenon is known as Ohm’s law.
To increase the use of ERG-2SJ121A, the resistor also offers adjustable variants. The resistance level is adjustable by turning a shaft connected to the resistor inside. This feature increases the versatility of a through-hole resistor, making it suitable for use in various circuit designs.
In addition, through-hole resistors have a wide range of tolerance, usually ranging from +/- 1% to +/- 10%. This tolerance indicates the deviation of the actual value from the nominal value stated on the resistor. This accuracy level of ERG-2SJ121A is higher compared to other resistor types.
In conclusion, ERG-2SJ121A is a very versatile through-hole resistor with high accuracy and wide application field. They are available with various tolerance and power ratings, from a few ohms to several megohms . All these features make ERG-2SJ121A resistors highly reliable and an ideal choice for use in both analog and digital circuits.
