Through Hole Resistors (also known as Leaded Resistors) have been used in virtually all types of electrical circuits and components. The MFR2WSFTF52-4K42 is a common type of through-hole resistor used in a variety of applications. In this article, we will discuss the application field and working principle of the MFR2WSFTF52-4K42.

Application

The MFR2WSFTF52-4K42 is a through hole resistor commonly used in a range of applications. These include low-voltage and medium-voltage power supplies, motor control circuits, electronic instrumentation, and medical equipment.

The MFR2WSFTF52-4K42 has a wide operating temperature range between -55°C to +150°C, making it suitable for use in high-temperature environments. It also has a high insulation resistance of 10,000M ohms, making it highly resistant to electric shock. Furthermore, it has a very high peak non-repetitive surge power rating of 1,500 watts, making it suitable for use in situations requiring high current.

Due to its robust design, the MFR2WSFTF52-4K42 is also suitable for use in low-voltage circuits and as protection against overvoltage in both AC and DC circuits. It is also UL approved, making it safe for use in applications involving hazardous locations.

Working Principle

The MFR2WSFTF52-4K42 works in a way that can be best described as the reverse of a semiconductor diode. Instead of the current flowing from the negative to the positive, the current flows from the positive to the negative. When a voltage is applied, the resistor will restrict the current, resulting in the voltage drop across it.

The amount of current that is allowed through a resistor is determined by its resistance. The higher the resistance, the lower the current will flow. The MFR2WSFTF52-4K42 has a resistance rating of 10KΩ, which is relatively low for a resistor of its size. As a result, it is suitable for applications requiring high currents.

Furthermore, the MFR2WSFTF52-4K42 is designed to dissipate heat. When a voltage is applied, the resistor will become hot due to the current flowing through it. To prevent it from being damaged, its internal structure is designed to efficiently dissipate this heat away from the component.

Conclusion

The MFR2WSFTF52-4K42 is a through hole resistor commonly used in a range of applications including low-voltage and medium-voltage power supplies, motor control circuits, electronic instrumentation, and medical equipment. It has a wide operating temperature range and a high insulation resistance, making it suitable for use in hazardous locations. Furthermore, it has a resistance rating of 10KΩ, making it suitable for applications requiring high currents. Finally, its internal structure is designed to efficiently dissipate heat, making it suitable for use in high-temperature environments.
