Through Hole Resistors are electrical components that provide a known resistance to the flow of electrical current. The CMF202K4000GKBF is one of the most common types of through hole resistors, making it a popular choice for a variety of applications. This article will explore the application field and working principle of the CMF202K4000GKBF resistor.

Application Fields for CMF202K4000GKBF Resistance

The CMF202K4000GKBF is a bulk metal foil resistor that is ideally suited for use in high-end audio applications, as well as in industrial and consumer electronics applications. These resistors are popular for use in power supplies, amplifiers, and signal conditioning circuits with high-frequency throughput. CMF202K4000GKBF through hole resistors are designed with an extremely high stability that allows for exceptional accuracy and precise voltage and current control.

The CMF202K4000GKBF does not require heat-sinking, making it an ideal choice for applications where environmental and safety regulations must be followed, and where there are space and weight limitations. These resistors can also be designed to handle extreme temperatures, from -55 to +155 degrees Celsius, due to their excellent temperature coefficient of resistance characteristics.

Working Principle of CMF202K4000GKBF Resistors

CMF202K4000GKBF through hole resistors use a bulk metal foil resistive element. This material is formed into a serpentine shape, with tight coils that contain the resistive material. The material can be formed into almost any shape, giving the user total control over where the resistive material is located. This enables users to optimize the resistor for their specific application.

To measure the resistance of the resistor, two probes are placed on opposite ends of the resistive element. As current is passed through the element, the voltage drop is measured between the two probes. This voltage drop is proportional to the resistance of the resistor, which can be determined from the Ohm\'s law formula.

Additionally, CMF202K4000GKBF resistors are highly durable. This is due to the use of metal foil in the resistive element. This material is highly inert and does not degrade over time, giving the resistor a service life of up to 50,000 hours. This makes the CMF202K4000GKBF a reliable choice for many applications.

Conclusion

The CMF202K4000GKBF through hole resistor is a popular choice for many electrical applications, due to its high stability, precise voltages and currents, and durability. These features make the CMF202K4000GKBF an ideal choice for industrial and consumer electronics applications, as well as for high-end audio applications. The working principle of the CMF202K4000GKBF involves using two probes to measure the voltage drop across the resistive element, and then using Ohm\'s law to calculate the resistance of the resistor.
