Through Hole Resistors are great choices when you need aggressive power dissipation with a large wattage rating margin. These resistors are most commonly used for power-based applications due to their incredibly high power rating. They come in many styles, shapes, and sizes, but all use the same form of heat-transfer for dissipating heat when current is flowing through the resistor.

55J250E is one of the Through Hole resistors;It is a three-terminal device designed to provide a stable resistance to an applied current. The 55J250E features a resistance value of 250Ω and maximum power dissipation capacity of 500 Watts at 70°C. This resistor uses a high-temperature soldering process, with an oxide coating to ensure long-term reliability and performance.

The resistor is made with two elements: an inner resistive element and an outer envelope of insulation. The inner resistive element is made up of a metal heating element which is typically a low-resistance type carbon film or wire wound resistor. It is encased in a metallic ceramic body or tin oxide covering. This ceramic metal body provides a low thermal impedance and high insulation resistance.

The 55J250E Through Hole Resistor is made for applications which require high power handling capacity. It is mainly used in power-intensive applications such as motors, power supplies, power converters, drives, power electronics, and more. It has excellent long-term stability and runs at high temperatures but still maintains its thermal characteristics.

The working principle of the 55J250E Through Hole Resistor involves the conversion of electrical energy into heat energy. When current passes through the resistor, the electrical energy is converted into heat energy due to the resistance in the wire. This heat energy is then dissipated into the environment. To ensure safety and performance, the resistor must be able to dissipate the heat efficiently, as well as withstand the high temperatures that result from this conversion.

The 55J250E Through Hole Resistor is an excellent choice for applications requiring power handling capacity and high-temperature operation. It is a reliable, low-cost solution for power-related applications where high power handling and thermal stability are needed. Furthermore, its wide resistance range make it an ideal choice for applications with different current requirements.
