Through Hole Resistors, most widely used due to their lower power capacity, are electronic components that are designed to prevent the passage of too much current through a circuit. They are generally used to limit the amount of current (amperage) through a circuit, or to divide voltage or current levels. The FKN7WSJR-91-1R2 is a through hole resistor which is designed to be used in power electronics applications such as motor control, switched-mode power supplies, and other high power track and switch applications.

The FKN7WSJR-91-1R2 features a large aluminum heatsink for improved thermal stability, high current surge capability, and wide range of temperature performance. It also features a thick layer of gold-plated protection around the metal body for protection against environmental threats. The device is composed of a contact base, an insulating layer, a metal core and two gold-plated contact pins. The contact base helps to guide the current through the resistor and is also responsible for the electrical performance of the resistor. The insulating layer helps to reduce electrical losses caused by the entry and exit of the current through the resistor. The metal core helps to dissipate heat, providing proper cooling performance for the resistor.

The working principle of the FKN7WSJR-91-1R2 is based on the resistance of the aluminum core inside the resistor. When a voltage is applied across the resistor, an electric current flows through the resistor and is limited by the resistance of the aluminum core itself. This limits the flow of the electric current through the resistor, providing the desired effect of voltage or current regulation. The gold-plated pins help to complete the electrical circuit between the power source and the resistor, allowing the current to flow through the resistor with minimal losses.

The FKN7WSJR-91-1R2 is designed for applications that require high power and current capability, as well as reliable temperature performance. It is also designed for use in a variety of environments, including high-humidity and high-temperature locations. The device\'s high current surge capability and wide temperature performance make it an ideal choice for motor control, switched-mode power supplies, and other high power track and switch applications.
