Through Hole Resistors: 90J120E Application Field and Working Principle

Through hole resistors, also known as lead mount resistors, are one of the most commonly used components in the electronics industry. They are components that are directly mounted onto printed circuit boards. The 90J120E is one such type, and it is widely used in various applications in both commercial and consumer electronics. In this article, we will discuss the 90J120E application field and its working principle.

90J120E Application Field

The 90J120E is a type of through hole resistor. It is a discrete resistor with a resistance value of 120 ohms and a power rating of 1/8 watt. This type of resistor is used in a wide variety of applications, such as amplifiers, digital systems, power supply systems, and audio equipment. It can also be used in any type of circuit in which resistance is desired. It is also used for current limiting purposes, and can also be used to regulate voltage.

90J120E Working Principle

The 90J120E through hole resistor works on the principle of Ohm’s law. Ohm’s law states that the current flowing through a resistance is proportional to the voltage applied to it, provided that the temperature remains constant. This means that if a particular resistor has a resistance of 120 ohms, the amount of current flowing through it will be proportional to the voltage applied to it. As the voltage increases, the current flowing through the resistor will increase too.

When the 90J120E device is connected to a circuit, it limits the current flowing through the device, and also reduces the voltage of the device. This is because of the resistance. The resistor will create a resistance in the circuit, through which the current needs to pass, and the voltage will drop. This will reduce the amount of current flowing through the device.

Conclusion

The 90J120E through hole resistor is a widely used component in the electronics industry. Its applications span across multiple fields, and it can be used for regulator and current-limiting purposes. It works on the principle of Ohm’s law, which states that the current flowing through a resistor is proportional to the voltage applied to it. This is why the 90J120E is able to reduce the voltage of the device when it is connected to a circuit.
