Through Hole Resistors: OF27GJE Application Field and Working Principle

Through hole resistors, also known as THRs, are resistive components that are mounted on printed circuit boards (PCB)s through a hole, as opposed to surface mount resistors, which are mounted on the exterior surface of PCBs. In the electronics industry, through hole resistors are used for EMI/RFI filtering, current limiting, voltage dividing, signal matching, power supply protection, and more. The OF27GJE model of THR is a nickel chromium series type, which has an operating temperature range of -40°C to 85°C and an insulation resistance of 100 megohms minimum.

The OF27GJE model is one of the most versatile through hole resistors on the market. It features a tape and reel packaging process for quick and efficient installation, as well as a ni-plated copper lead frame for strength and longevity. The OF27GJE THR also features an insulated screw head for heat resistance, and an epoxy-based design for increased reliability in extreme conditions. Through hole components are also one of the best choices for applications where flexibility and reliability are paramount.

The working principle of the OF27GJE THR is an application of ohm\'s law. Ohm\'s law states that the current I passing through a resistor R in a circuit is proportional to the voltage V applied across it, I = V/R. This means that the amount of current that flows through a THR is determined by the amount of voltage applied across it, and vice-versa.

In the OF27GJE THR, the voltage across the resistor is controlled by adjusting the body length. When more voltage is applied to the THR, the body length increases, thus increasing the resistance. This process can be repeated until the ideal resistance value is reached. Through this process, the OF27GJE THR can be set to provide an exact desired resistance. This makes it an ideal choice for applications where accuracy is paramount.

In addition to its adjustable body length, the OF27GJE THR also features an internal heat sink, which serves to dissipate excess heat and prevent thermal runaway in critical applications. The THR also features a flame retardant epoxy coating, which helps to protect the THR from mechanical and electrical wear and helps ensure that it will hold up to flexing and vibrations.

In summary, the OF27GJE THR is a versatile through hole component that offers reliability and accuracy for a wide range of applications. It features an adjustable body length to set the desired resistance, as well as an internal heat sink for excessive heat dissipation. The THR also features a flame retardant epoxy coating for extra durability and protection. With its reliable performance, accuracy, and versatility, the OF27GJE THR is an excellent choice for both prototyping and production applications.
