Through Hole Resistors, such as FCR50SJT-52-20R, use a simple yet effective design to achieve a precise resistance value in connection with a circuit. A through-hole resistor is an electrical component that reduces the current flow through a circuit. It is a two-terminal device that consists of a ceramic body coated with resistor material, which is a thin film of carbon particles. It is designed to resist the flow of electrons and it is often used to provide a range of resistances from a few ohms to tens of kilohms.

Application Field

Through-hole resistors are commonly used in a wide variety of industries and applications, due to their cost-effectiveness and reliability. They are often used in low-power applications such as automotive, industrial, medical, and consumer electronics. In automotive applications, they are used for circuit protection, motor speed control, and power distribution. In industrial applications, they are used for load balancing and temperature sensing. In medical applications, they are used for power delivery and measurement. Additionally, they are found in consumer electronics such as computers, televisions, and cell phones.

Working Principle

The resistance offered by a through-hole resistor depends on its construction. A conventional through-hole resistor uses a ceramic body with a thin film of resistor material deposited on it. The resistor material produces a range of resistances, from a few ohms to tens of kilohms. The material used for the resistor film is usually a carbon composition, in which the amount of carbon in the material varies, producing a range of resistances. The amount of carbon used can be adjusted by carefully controlling the deposition processes that take place during manufacture.

In operation, the through-hole resistor behaves like an insulator, meaning that no current will pass through it, and thus no voltage will be developed across it. The basic function of the resistor is to reduce the current flow through the device. This is done by limiting the number of electrons that can pass through at any given time. By increasing the size of the resistor, more electrons are blocked, and the current is further reduced.

The resistance value of a through-hole resistor is determined by two factors: the size of the resistor body and the amount of resistor material deposited on it. By using a larger resistor body, more resistor material can be deposited, and thus the resistance value can be increased. By using a smaller body, the resistance value can be reduced. By carefully controlling the manufacturing processes, the resistance value can be precisely controlled.

In summary, the FCR50SJT-52-20R is a through-hole resistor that offers a wide range of resistance values in a cost-effective and reliable package. The resistance value is determined by the size of the resistor body and by the amount of resistor material deposited on it, allowing precise control of the resistance. With its low-power applications, it is a commonly used component in the automotive, industrial, medical, and consumer electronics industries.
