Through Hole Resistors - FCB22K2J Application Field and Working Principle

Through hole resistors are some of the most commonly used resistors in the electronics industry. They are widely utilized due to their low cost, simplicity, and two-terminal configuration. The FCB22K2J is a type of through hole resistor that is commonly utilized in various applications. This article will discuss the application field and working principle of the FCB22K2J.

Application Field

The FCB22K2J is a carbon film through hole resistor, and as such is ideal for applications where it is necessary to protect sensitive components from overloads or surges. It is also commonly used in switching and regulating circuits, satisfying applications where accurate currents and voltages are required such as power supply units.

It is a popular choice for commercial applications of all kinds, from consumer electronics to industrial equipment and agriculture to more specialized areas like automotive, aerospace, and medical applications. One notable example is its use as a bleeder resistor in many high voltage and high power circuits. Due both to its robustness and cost-effectiveness, it is usually the preferred choice.

Working Principle

The FCB22K2J is a two-terminal resistor. Its two terminals can be soldered onto a printed circuit board, forming a simple electrical connection. The resistor works by reducing the flow of current from one terminal to the other. The amount of resistance offered by the FCB22K2J can be adjusted by changing the length of its element, which consists of a layer of carbon film between two metal plates.

The FCB22K2J employs what is known as a non-inductive stay flat winding technique for its construction. This technique allows the resistor to remain relatively flat, even under high temperatures or power loads. To further protect its elements from distortions due to extreme temperature or power fluctuations, the resistor is also typically surrounded by a glass coating.

The FCB22K2J has a wide range of operating temperature ranges, between -55 and +125 °C. This makes it suitable for almost any kind of application, from low-power to high-power. Additionally, the resistor has a low noise level and is relatively tolerant of high voltage and current levels as well as high temperatures.

The FCB22K2J has numerous advantages, including its small form factor, low cost, and robustness. These factors make it suitable for a variety of applications in both commercial and industrial settings and have made it one of the most popular through hole resistor designs on the market.
