Through Hole Resistors

A through-hole resistor is an electronic component that supplies a specific amount of electrical resistance in an electric circuit. It is typically constructed from a cylindrical body of insulating material with two metal contacts on either side. Through-hole resistors are most commonly used to prevent and reduce excess current, which prevents devices from overheating or releasing too much power. In order to successfully use a through-hole resistor, it is important to be aware of its application field and working principle.

Application Field

Through-hole resistors are found in a variety of devices ranging from circuit boards to high voltage power supplies. They are used to help regulate the flow of electricity, reduce losses between paths, and protect components from excessive voltage or current by limiting the total current that can pass through the circuit. Through-hole resistors are also able to absorb and dissipate heat more effectively than other types of resistors, making them particularly well-suited for high current and high voltage applications.

The OJ6245E-R52 is a through-hole resistor, designed for high-temperature applications. It features a wide range of resistance value tolerance, is rated for up to 500W of power dissipation and can handle a maximum operating temperature of +175 C. This makes it suitable for a variety of applications, including industrial and automotive electronics, power electronics, and telecommunication and instrumentation systems.

Working Principle

A through-hole resistor works by restricting the flow of electrical current between two points. When an electric current is passed through the resistor, a voltage drop is created. This drop is determined by the resistance value of the resistor. The higher the resistance value, the greater the voltage drop across the resistor.

The OJ6245E-R52 through-hole resistor utilizes a carbon composite composition to effectively control the electrical current. This allows for a precise amount of resistance to be obtained, as well as excellent reliability and stability in operation due to its high-temperature operation rating.

Conclusion

Through-hole resistors are an essential component in many electronics. They are used to control the flow of electricity in a circuit, reduce power losses, and protect components from excessive voltage or current. The OJ6245E-R52 is a through-hole resistor that is designed specifically for high-temperature applications, and its carbon composition allows for precise resistance control and reliable operation.
