Through Hole Resistors

Resistors come in different package and type, in this section we will discuss the Through Hole Resistor, or RNR60H3651FRRSL application field and working principle.

What is Through Hole Resistor?

Through Hole Resistors, also known as THRs, are discrete components used in electrical circuits for precise resistance control. They are widely used in the manufacture of process control, temperature measurement, automation and other equipments. They can be used to reduce electrical noise, increase or decrease a signal\'s voltage or current, dissipate heat, and control frequency.There are many types of through-hole resistors available, including standard resistors, potentiometers, multiturn potentiometers, precision resistors, surge or transient suppressors, and adjustable resistors.

Types of Through Hole Resistors

Various types of through hole resistors function differently depending upon the type of resistance they provide. Some of the types of through hole resistors are:

• Standard resistor – These are fixed resistors. They are available in various sizes. These resistors come with the same resistance at any given temperature.
• Potentiometer – These are resistors with three terminals. They are used to control current for a wide variety of applications. The resistance between the terminals can be varied by turning a knob.
• Multiturn potentiometer – These are special type of potentiometers that offer higher precision and accuracy than standard potentiometers. They are suitable for applications that require precise resistance control.
• Surge or transient suppressors – They are also called varistors. These resistors offer high resistance when the voltage amplitude is high and low resistance when the voltage drops. They are used to protect circuit components from power surges or transients.
• Adjustable resistors – These resistors are used to adjust electrical parameters in the circuit, such as gain, frequency or feedback. Some adjustable resistors have variable angles of rotation and others have multiple stages for selecting a resistance setting.

Components and Working Principle of Through Hole Resistors

Through hole resistors are made up of three main components – a resistance body, a terminal connector and a capacitor. Each component is numbered according to its polarity or resistance. The main purpose of these resistors is to reduce the resistance of a circuit. The working principle of a through hole resistor is based on the fact that currents flow from high potential to low potential. When the high and low potentials of a circuit are connected through a resistor, the flow of current is reduced and the resistance of the circuit is increased.

The resistor body is created by heating a section of metal alloy and then grinding it to the required shape. This grinding process results in a tiny metal disk called the resistance body, which contains the resistance. This is connected to two terminals, which act as the connectors of the resistor.

The resistor and its terminals are then covered in epoxy to protect the resistor from external damage. Finally, a capacitor is attached to the resistance body to increase its capacitance. Typically, the size of a resistor is directly proportional to its capacitance, and this affects the level of resistance produced by the resistor.

The function of a through-hole resistor is to increase the resistance of a circuit without affecting the other components. This allows it to control the voltage and current of a circuit. The resistance of a through-hole resistor is adjustable, depending on the size of the resistor.

Applications of Through Hole Resistors

Through hole resistors are widely used in many electronic applications. They are used to dissipate heat from circuit components, to reduce noise in high frequency applications, and to control the current and voltage in circuits. They are also used in the fabrication of transistors, diodes, and other electronic components. Through hole resistors are used in automotive, medical, aerospace, and industrial applications, in which high precision and accuracy is required.

Through hole resistors are also used in communications and data processing equipment, where they can be used to control the speed or communications of a circuit, or as a protective agent against electromagnetic interference or surges. They are also used in power supplies, in which they provide a measure of protection from over voltage or over current.

Conclusion

Through hole resistors are a type of discrete component used to control current in electrical circuits. They come in different sizes and can be used in various applications, from controlling current in circuits, to dissipating heat, to reducing noise in high frequency applications. Through hole resistors are used in automotive, medical, aerospace, and industrial applications, in which high precision and accuracy is required.
