Introduction: Through Hole Resistors are a type of power electronic device with an internal resistance for use in different kinds of applications. This is usually of two types; non-inductive type and the inductive type. In most of the applications, they are used to control high voltage, reduce the current flow, maintain a certain temperature, and improve the accuracy of the application. Through Hole Resistors have a wide range of applications such as the automotive and aircraft industry, telecommunications, consumer electronics, and medical and industrial applications.

90J2K2E application field and working principle: 90J2K2E is a through hole resistor, specifically designed for high-power operation in short duty cycle applications. It can withstand up to 200A continuous, 500A surge current, and up to 500V voltage. It is also practically immune to vibrations due to its robust construction. The 90J2K2E through hole resistor has various applications such as alternators in automobiles, start/stop solenoids, and fuse blow devices for safety. It is also suitable for power supplies, motor speed control systems, and different kinds of power amplifiers. Apart from automotive, it can also be used in different industrial applications such as machine tools, HVAC, pumps, and power systems.

The 90J2K2E through hole resistor has an internal resistance rating of 0.4 ohm at 200A, 0.7 ohm at 400A, and 1.1 Ohm at 800A. It’s working power principle is based on dissipating heat using a coil that limits the flow of current. The size of the coil determines the amount of current that can flow through the resistor and therefore its resistance. This means that the more the coil size, the less the current that can flow. The 90J2K2E through hole resistor is made up of a high-temperature resistant ceramic, a metalized shield, and an insulative band. When an alternating current passes through the 90J2K2E resistor, the coil generates a magnetic field and this creates electric resistance. The voltage across the resistor is then divided according to the formula of Ohm\'s law.

Advantages: The main advantage of the 90J2K2E through hole resistor is its ability to provide accurate and reliable control of the current, voltage, and temperature. It is also extremely durable due to its robust construction. Additionally, it has a wide range of applications across various industries. It can be used in automotive, industrial, consumer electronics, and medical applications. It is also very easy to install and requires minimal maintenance. Furthermore, it is resistant to shocks, vibrations, and extreme temperatures.

Disadvantages: The 90J2K2E through hole resistor is not suitable for high power operation in long duty cycles. Additionally, due to its internal resistance, it can lead to loss of energy during conversion and can increase the electric bill significantly.

Conclusion: The 90J2K2E through hole resistor is a useful power electronic device, suitable for use in a variety of applications. It can provide accurate and reliable control of current, voltage, and temperature, and is highly durable due to its robust construction. It has various advantages such as easy installation, minimal maintenance, resistance to shocks, and vibrations. However, it is not suitable for high power operation in long duty cycles and can lead to substantial energy loss during conversion.
