Through Hole Resistors

The CMF55432K00BHEB is a through hole resistor with a plated, solderable, terminal mounting. It has two types of contacts, surface mount and thru-hole, with an extremely low resistance value of 0.5 ohms. It is designed to provide a reliable path for resistance and current in a broad range of applications in the automotive, power, industrial, audio/visual, and computer industries.

Application Field

This through hole resistor is commonly used in automotive systems in place of largely larger and more expensive power resistors, such as copper-wound and ceramic power resistors. Due to its cost-effectiveness and high performance, it is also used as a replacement for standard surface mount or thru-hole resistors across a variety of other applications as well.

In automotive applications, this resistor can be used to control the current and voltage of an engine’s fuel injection system. It can also be used to limit the speed of windshield wipers and radio signals, to regulate lamp wattage, and to minimize noise transmission and spark suppression. Its usage in the power industry includes over-voltage protection of power supplies, motorized applications, and current measurements. In the industrial sector, it is used for energy management and load control in industrial machinery.

This through hole resistor is also widely used in the computer industry, particularly for motherboard and power supply devices. In the audio/visual industry, the resistor provides low noise levels and sound dampening to various audio systems. Its enhanced thermal capabilities have also made it suitable for use in downlight systems and other lamping applications.

Working Principle

The working principle of the CMF55432K00BHEB through-hole resistor is fairly straightforward. It works by limiting the amount of current that can pass through it. Through the application of negative resistance dynamics, the resistor can keep the voltage at a specific level. As the current passes through the resistor, its negative resistance will act to restrict the current from going beyond the set voltage level.

The resistor also uses a special design to dissipate heat. On the surface of the resistor, there is an insulation layer that helps protect against arcing and sparking. In addition, this protection layer helps dissipate the heat quickly, thus increasing the resistor’s efficiency. It is also designed with a low temperature coefficient, enabling it to maintain a consistent resistance level even when subjected to thermal stress.

Conclusion

The CMF55432K00BHEB is a through hole resistor with a low resistance value of 0.5 ohms and two types of contacts, surface mount and thru-hole. Its cost-effectiveness and high performance makes it suitable for a wide range of automotive, power, industrial, audio/visual, and computer applications. The resistor works by limiting the amount of current that can pass through it, providing a reliable path for resistance and current. With its special design and thermal capability, it can operate efficiently and consistently even when subjected to thermal stress.
