Introduction
Through hole resistors are a type of passive component found in many electronic circuits. The 45FR20E is a three terminal resistor, mainly used to fix a machine-generated value in various circuits, helping to control current flow. This paper will provide an overview of the fields in which they are commonly used and outline the working principle of the 45FR20E.
Application Fields
The 45FR20E has a wide range of uses due to its simple design, providing overvoltage and current limiter protection when used as a discrete component in many different kinds of circuits. They are widely used in telecommunications and consumer radios, where they are used to maintain signal strength and prevent damage to sensitive circuits.The 45FR20E can also be found in industrial electronic equipment, such as touch screen interfaces and factory automation systems, where they are needed to provide accurate resistance values to ensure reliable operation. Additionally, these resistors are used in automotive, HVAC, medical, and automation systems.These resistors can also be used in high-current applications, such as welding, and automotive engines and transmission systems. In such applications, their resistance to high-currents and their ability to dissipate heat are essential for safe and reliable operation.
Working Principle
The 45FR20E is a three-terminal resistor that works using the principle of Ohm’s Law as follows. When a voltage is applied to the first terminal, the current flows through the resistor and creates a voltage drop across it, proportional to the current and resistance applied. This voltage drop is then applied to the second terminal.The third terminal is used to adjust the resistance of the resistor, as adjusting the resistance changes the voltage drop of the resistor. The third terminal also allows for the use of the 45FR20E in various applications, as different resistance values can be obtained by setting the third terminal to different positions.In terms of materials used, the 45FR20E is typically made from ceramic and metal materials. The ceramic material offers excellent electrical resistance characteristics, while the metal material helps to dissipate heat generated by the resistor. The use of these specific materials helps to provide a good balance of features such as accuracy of resistance value, energy dissipation, and durable performance.
Conclusion
The 45FR20E is a three-terminal resistor that is commonly used in many electronic circuits. They are mainly used as a fixed value component, helping to control current flow in various circuits. The 45FR20E has a wide range of applications in telecommunications, consumer radios, industrial equipment, automotive, HVAC, medical, and other automation systems. The 45FR20E uses the principles of Ohm’s Law, and is typically made from ceramic and metal materials for excellent electrical resistance characteristics and heat dissipation.
