Through Hole Resistors

Through hole resistors, also called axial lead resistors, is a type of resistor equipped with two axial leads and a cylindrical body that can be mounted through a punching hole in the device. They are most commonly used in DC circuits, such as those found in automotive, consumer and communication applications.The CMF50250R00FEEK is a through hole resistor that operates with a relatively low input voltage to provide the necessary power to an electrical system. It is also designed to provide moderate power overheat in the event of an output overload. The resistor features an 8-pin DIP (dual in-line package) design with two axial leads made of nickel-plated phosphor bronze alloy. This provides excellent noise immunity and makes it suitable for use in automotive and consumer applications.The operating principle of the CMF50250R00FEEK is based on a voltage divider circuit. This circuit operates by dividing the input voltage and providing a reduced voltage at its output. This reduced voltage is then further reduced by the resistor’s dynamic resistance, which is determined by the size of the resistor and the amount of current flowing through it. In addition, this resistor also has a very low temperature coefficient, meaning it is less affected by a change in temperature than other types of resistors.The CMF50250R00FEEK through hole resistor is especially suited for applications in which load current values remain within a 0.2A to 2.5A range, such as in automotive power systems. In these applications, it is designed to provide excellent reliability and additional protection from high voltage transients. The resistor is also able to resist short circuit overload conditions and its dynamic resistance is able to cope with voltage surges in industrial, telecoms and automotive applications. In the automotive sector, it is particularly suitable for applications using an integrated electronic fuel injection system (EFI), as it helps protect against high voltage transients.Overall, the CMF50250R00FEEK is an excellent through hole resistor that provides reliable protection and stability in many types of applications. Its small size coupled with its ability to withstand short circuit overloads make it an ideal solution for automotive, telecoms and industrial applications. It also has the added benefit of providing low noise immunity and a low temperature coefficient, meaning it is more resilient to changes in temperature than other types of resistors.
