Through hole resistors are resistors that are composed of a wire wrapped around a filled ceramic cylinder or a tube filled with a resistive material. The material usually used is either tungsten, a noble metal, or carbon. These kinds of resistors are generally manufactured to obtain high power ratings and can handle higher power loads than standard surface mount resistors. In this paper, we will be examining the MJ2941FE-R52 application field and working principle.

Rated Power & Voltage

The rated power of the MJ2941FE-R52 through hole resistor is 5W at 25°C. It has a voltage rating of 500V and a resistance range of 0.5 Ω - 100 KΩ. The resistor is made of a metal oxide film with a resistance element that is wire-wound. It has a maximum operating temperature of 150°C and a temperature coefficient of 0.2%/K.

Mounting & Terminals

The MJ2941FE-R52 is a through hole resistor and therefore requires mounting onto printed circuit boards. The resistor has two lug terminals at each end of the resistive element for maximum power using the through hole mounting technique. Depending on the manufacturer, the product may come with a top or bottom mounting configuration.

Features & Benefits

The MJ2941FE-R52 offers excellent performance over a wide range of temperatures and is designed to withstand high power loads. Other features include low power losses at high operating temperatures, a high load capacity, high dielectric strength, and excellent insulation properties. The resistor also has a fireproof construction and is non-toxic, making it safe for use even in highly hazardous environments.

Applications

The MJ2941FE-R52 through hole resistor is most commonly used for the power supply circuit design in electronic equipment such as radar, communication systems and high-speed switching power supplies. It can also be used in motor speed control and in various industrial control systems and industrial motor applications. It is also suitable for use in military applications such as in guidance systems.

Working Principle

The MJ2941FE-R52 through hole resistor works on the principle of Ohm’s Law, which states that current is directly proportional to the voltage applied and inversely proportional to the resistance present. This is to say that the current passing through the resistor is directly proportional to the voltage across the resistor and inversely proportional to the resistance of the resistor. This is because when voltage is applied to the resistor, it causes the resistor to consume power, which in turn causes the resistor to heat up, reducing its resistance.

Conclusion

The MJ2941FE-R52 through hole resistor is a versatile and reliable component that is designed for use in a wide range of applications and environments. It offers high power ratings, high dielectric strength, excellent insulation properties, and a fireproof construction. It is also non-toxic and requires simple mounting techniques. The resistor works on the principle of Ohm\'s Law, which states that current is directly proportional to the voltage applied and inversely proportional to the resistance present.
