Through Hole Resistors

Through hole resistors are resistors that are soldered into printed circuit boards (PCBs). They are extremely useful for a variety of applications and come in a variety of sizes and shapes, depending on the specific application requirements. Resistor technology has advanced greatly over the years, with different types of resistors offering better precision and durability.

FKN2WSJT-52-22R Application Field and Working Principle

The FKN2WSJT-52-22R is a through hole resistor that is designed for general-purpose applications. It has a large power rating for dissipating heat and can withstand a wide variety of environmental conditions. The resistor is made of high-quality, surface-mounted metal alloy layers with a thick epoxy coating. The metal alloy provides the electrical resistance, while the epoxy coating provides insulation to protect the circuitry beneath.The FKN2WSJT-52-22R is a through-hole, power resistor offering excellent long-term reliability and stability. It is a popular, cost-effective solution for a wide range of applications including power supplies, power electronics, LCD backlights, and automotive applications.On the technical side, the FKN2WSJT-52-22R features a wide operating temperature range (-55 to +155 degrees Celsius) and a low inside series resistance (<2mΩ). It has a maximum power rating of 15 watts, and can handle up to 100 volts of RMS voltage. It also features a tight tolerance of ±5%, as well as high temperature cycling capabilities.The working principle of a through-hole resistor is relatively simple. When a current flows through the resistor, the electrical energy is converted into thermal energy. As the temperature of the resistor increases, the resistance value decreases, allowing more current to flow through. This effect is known as self-heating.In applications where the temperature needs to remain constant, such as with power supplies or regulated circuits, special components are used to counteract the self-heating effect. These components, known as "temperature compensators", help to balance the resistance value by keeping the temperature of the resistor stable.The FKN2WSJT-52-22R is a great solution for moderate and high-power applications. Its wide operating temperature range and excellent stability make it an ideal choice. Additionally, its low series resistance makes it a good choice for applications that require an intense current flow.
