The CMF55298K00BER6 through hole resistor is a device used to accurately control the passage of current 24 hours a day, seven days a week. It either limits or provides a source of resistance in electronic circuits, preventing the passage of excessive amounts of current, even for high voltage sources. Through hole resistors are also referred to as “plug” or “rotator” resistors and are often found in many types of industrial equipment, especially large appliances. The resistor is used to protect other components, primarily valves, and prevent too much current from entering the system. There are many different types of through hole resistors, which can be identified by their distinctive shapes and colors.
The CMF55298K00BER6 through hole resistor is designed with two major components: a ceramic disk body and a metal body. The ceramic disk body houses a layer of electrolytic conductive material that is electrically connected to two straight metal pins and is wired to each leg of the resistor. The metal body surrounding the ceramic disk acts as a shield against environmental elements and prevents corrosion. It also acts as an insulator and minimizes the effects of transients.
In application fields, these CMF55298K00BER6 through hole resistors are often used where precise current control is required, such as in the operation of television sets or automotive systems. They are also used for safety-critical applications, for example in medical devices, fire alarm systems, or machine control systems. In addition, this kind of through hole resistors are often employed in the communication systems, including servers, routers, switches and cell phones.
The working principle of CMF55298K00BER6 through hole resistor lies in its ability to limit the current. As current flows into the resistor, a voltage drop across the two metal pins is created. This voltage drop is proportionate to the current passing through it. This voltage drop is transferred to the ceramic disk where electrons are then scattered in the intricate pattern of electrolytic paths , thereby producing a resistance. This resistance prevents the current from passing through, thus limiting the current and protecting other components from being damaged by over-current.
In conclusion, CMF55298K00BER6 through hole resistors offer reliable and precise current control. Their low cost, ease of use and robust construction make them a popular choice for many industrial applications. They are even used in safety-critical applications, where it is important to ensure that the current does not rise to a dangerous level. The working principle of the through-hole resistor is also quite simple; the voltage drop produced across the two metal pins is transferred to the ceramic disk, creating resistance and limiting the current.
