Through Hole Resistors

CMF555R1700FKEA, also known as through hole resistors, are a type of electrical component used to control the flow of electricity in circuits. They are constructed from two metal plates which are separated by an insulator, typically a ceramic layer. When a voltage is applied to the resistor, the electric current flowing through it produces a voltage drop across the resistor. By adjusting the resistance, the current can be regulated, allowing for a wide range of applications.

Application Field

Through hole resistors are widely used in the automotive, industrial, medical and consumer markets. Some of the most common general applications for these components include: regulating power supply voltages, controlling speed in motors or generators, and providing additional means for current control. More specific applications include noise suppression, signal conditioning, RF amplification, waveform sharpening and signal isolation.

Working Principle

The working principle of a through hole resistor is based on Ohm’s law, which states that the voltage across a resistor is equal to the product of the current flowing through the resistor and its resistance. The voltage drop is proportional to the product of the current passing through the resistor and its value. This relationship allows the resistance to be adjusted to achieve the desired current, making the resistor a very useful component in circuit design.

When voltage is applied to the resistor, the current flows from one plate to another. This creates a voltage drop across the resistor that depends on the resistance of the resistor. As the applied voltage increases, the current flowing through the resistor increases until it reaches its maximum value. At this point, the voltage across the resistor is equal to the applied voltage. By adjusting the resistance, the current can be increased or decreased.

In addition, the resistor can be used to limit the current flow in a circuit by setting the resistance to be higher than the minimum required for the current load. This is known as current limiting and is used in many applications, such as protecting a transistor or semiconductor device from over-current.

Finally, the voltage drop across a resistor can be utilized to measure the current flowing through the resistor by connecting a voltmeter in series with the resistor. This is known as a Voltage Divider and is widely used in sensing and control applications.

Conclusion

Through hole resistors are a type of electrical component used to control the flow of electricity in circuits. They are constructed from two metal plates which are separated by an insulator, typically a ceramic layer. The resistor’s ability to control current by adjusting its resistance makes it an invaluable component in many circuits. The versatility of through hole resistors is why they are so widely used in a wide range of industries, from consumer electronics to industrial automation.
