Through Hole Resistors are electronic components that are used to limit or control the flow of current through a circuit. These resistors are found in a variety of applications, from the basic household electrical circuit to complex industrial applications. One type of resistor that is commonly used is the OF125KE series resistor. This resistor is made with a thick film construction and comes in a variety of overcurrent protection options.

The OF125KE series resistor is a thick film based resistor with a power rating of 5 watts. This resistor has a resistance range of 1 milliohm to 92 kiloohms. The resistor also has a tolerance range of 1-2 percent and a temperature coefficient of ±200 ppm/°C. The resistor is designed to provide maximum current handling capabilities under high temperature, as well as over-current protection.

The OF125KE is a popular choice for applications where high current-handling capability, high temperature resistance, and over-current protection are required. It is especially well-suited for use in medical, automotive, consumer electronics, and industrial applications. The resistor can also be used in very small spaces as it comes in a compact size.

The working principle of the OF125KE resistor is relatively simple. It basically acts as a resistor by limiting the current through its resistance. This resistor is composed of a thick film that is layered on a ceramic substrate and connected to two or more leads. The leads are typically gold-plated or silver-plated depending on the application. The resistive layer is connected to a voltage source, and when current flows through it, a voltage drop is formed across the resistor.

The contact resistance of the OF125KE is also very low, making it suitable for use in high-impedance applications, such as medical, automotive, and many industrial applications. This low contact resistance allows current to flow through the resistor without a significant drop in voltage. Additionally, the resistor also exhibits excellent stability in high temperatures, making it a good choice for applications that require reliability under high temperature.

When choosing an OF125KE resistor, it is important to consider the environment in which the resistor will be used. The resistor should be able to withstand the temperature, current, and humidity of the environment in which it will be used. It is also important to consider the size and shape of the resistor, as it should be able to fit the space in which it will be used. Additionally, it is important to make sure that the resistor can handle the current that it will be expected to handle.

The OF125KE series resistor is a valuable component used in a variety of applications. It is constructed from a thick film substrate and comes in a variety of over-current protection options. It is a highly reliable resistor with a low contact resistance that allows for excellent current flow at high temperatures. The OF125KE series resistor is a good choice for a variety of applications that require high current-handling capabilities, high-temperature resistance, and reliable over-current protection.
