Through Hole Resistors

Through-hole resistors are a type of resistor used in electronic circuits that are characterized by a body that is designed to be mounted through a hole in a printed circuit board (PCB) or chassis. The component has two electrical connections, the leads, which are found at either end of the body. These leads are usually of equal length so that the component can be mounted in either direction.

The MJ14R0FE-R52 is an example of a through-hole resistor. It is an axial through-hole resistor that has an insulation diameter of 12.7 mm and a body length of 6.2 mm. It has a rated power of 14 W, a resistance range of 0.033-51 Ohm and a tolerance of ± 5%. It has a temperature coefficient of 100ppm/K, a working temperature of -55–155°C, and a maximum operating current of 1.5 A. This type of resistor is suitable for applications that require low noise and high stability.

Application Field

The MJ14R0FE-R52 through-hole resistor is typically used in industrial, consumer, medical, automotive and aerospace applications. It is commonly used in power supplies, LED drivers, automotive circuitry, and even medical and military equipment and sensors. It can be used to control current in motor control circuitry, filter power, and maintain electrical power distribution. Furthermore, it can be used for voltage-controlled oscillators and voltage-controlled amplifiers.

Working Principle

The MJ14R0FE-R52 resistor works on the principle of electrical resistance. The resistor is composed of a material with a certain electrical resistance value, and its resistance is determined by its length, width, and thickness. When a voltage is applied across the resistor, it will create an electric current in opposition, which is known as the resistance. This opposing current will in turn generate energy, usually in the form of heat, and dissipate it. The amount of current conducted by the resistor is determined by its resistance value, hence its name.

As mentioned earlier, the MJ14R0FE-R52 has a rated power of 14 W and a resistance range of 0.033-51 Ohm and a tolerance of ± 5%. This limits the amount of current that the resistor can conduct. Higher tolerance means more current and therefore greater power can pass through the resistor before it overheats. The temperature coefficient of 100ppm/K means that the resistance of the resistor increases by 100ppm for each degree increase in temperature.

In summary, the MJ14R0FE-R52 is a through-hole resistor with excellent features for medium to low power applications. It is suitable for a wide range of applications including industrial, consumer, medical, automotive and aerospace, and can be used for both voltage and current control. It has a rated power of 14W, a resistance range of 0.033-51 Ohm, and a temperature coefficient of 100ppm/K, making it a practical and reliable choice for through-hole resistors.
