Through Hole Resistors are electronic components that are essential to the proper functioning of circuits. Primarily used to limit current flow in circuits, they come in a variety of styles and configurations, each suited to specific applications. One such configuration is the CMF70448K00DERE, a through hole resistive element. In this article, we will examine the application field and working principle of the CMF70448K00DERE through hole resistor.The CMF70448K00DERE through hole resistor is manufactured by the Amphenol Corporation, a leading supplier of interconnect and electromechanical devices to the automotive, telecommunications, and consumer electronics markets. The CMF70448K00DERE is designed primarily for automotive use and is most commonly used in 12 Volt and 24 Volt systems. It can be used in a variety of vehicles, including cars, trucks, and boats.The primary function of the CMF70448K00DERE is to limit current through a circuit to a preset value. This is done through the use of a metal-oxide varistor, or MOV, and an energy reservoir capacitor. The current passes through the resistor and is limited by the MOV. The MOV has a minimum breakdown voltage Vz, and the resistor is connected in an “L” shape, with a resistor in the middle. This configuration allows for current limitation at higher voltages. The MOV thus works as a protection device against overvoltage and eliminates EMI (electromagnetic interference), which improves the quality of the output signal. The energy reservoir capacitor is used to store energy prior to it going through the resistor. The capacitor is charged and discharged at a constant rate, so that the current passing through the resistor does not exceed the preset limit. Energy is stored in the capacitor and released through the resistor if a transient overload passes through the system.The CMF70448K00DERE is UL (Underwriter’s Laboratories) approved and is rated at 12 Volts and 25 Amps. It is a durable and reliable component, and can withstand temperatures up to 200°C (392°F). The resistor is designed for quick and easy installation, and most installations require no additional wiring or hardware.The CMF70448K00DERE can be used in a variety of applications, including automotive systems, heavy-duty trucks, ATV/UTV vehicles, and motorbikes. It can also be used in marine circuits, such as audio systems and alarm systems. The resistor is UL approved, making it safe for use in hazardous applications. Additionally, the resistor is RoHS compliant, ensuring it is free of hazardous materials.In summary, the CMF70448K00DERE is a robust and reliable through hole resistor that is designed for automotive applications. It limits current through a circuit to a preset value by using a MOV and an energy reservoir capacitor. It is UL approved, RoHS compliant, and capable of withstanding temperatures up to 200°C (392°F). The resistor is also quick and easy to install and can be used in a variety of applications.
