Through Hole Resistors are widely used in various fields, from consumer electronics to industrial control panel applications. They are also known as THRs, because their size and shape are very similar to a regular through-hole. OF121JE is a resistor commonly used for high power applications to resist higher currents than regular THRs, while at the same time remaining cost efficient.

The OF121JE resistor is a 2W axial through-hole resistor that has a diameter of 12.1mm and a length of 14.4mm. It is made up of a nickel plated cylindrical aluminum will with a ceramic coating on the outside. The resistor contains a conducting core that is then insulated with heat-resistant material, typically glass braid. Its purpose is to regulate current and voltage in various electrical devices, playing a crucial role in power management and system performance.

The working principle of the OF121JE through hole resistor is simple. It works by reducing the amount of electrical current flowing through it, allowing controlling and dissipating heat. The resistor\'s electric resistance and temperature coefficient are determined by the type, size, shape and material of its core.

When an electric current is applied to the resistor, it works by increasing the resistance of the connection, and decreases the current. This allows for controlling, regulating, and limiting currents. The higher the resistance, the lower the current. It also works as a safety device, as it prevents excessive heating and potential short circuits. Additionally, increasing the resistance may also be necessary to ensure the device operates at the correct voltage.

OF121JE has many application fields, such as temperature control, audio systems, power circuits, drives, motor control, HVAC systems, heaters, switching circuits, audio amplifiers, instrumentation circuits, and various other industrial and consumer products. It can also be used in a variety of environments, from extreme hot and cold temperatures to high-vibration areas. It is also a great choice for electrical and environmental safety applications, as the device provides protection from voltage spikes and excessive currents.

The OF121JE through hole resistor also offers superior durability and reliability when compared to other resistor types. Its design helps to mitigate moisture, humidity, and chemical exposure, providing a high-quality solution that can withstand long-term use. Additionally, since the device is designed to be cost-effective, it is an ideal solution for cost-sensitive applications.

Overall, the OF121JE through hole resistor offers a wide range of benefits, from cost-effectiveness to high temperature stability. Its simple working principle and wide application field make it an ideal choice for various industrial and consumer products. In addition, its superior durability and long-term reliability make it a great solution for different electrical and environmental applications.
