Introduction to Through Hole Resistors

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors are used in various electrical circuits for several purposes, the common ones being to limit current, to divide voltage and to bias active elements. There are many types of resistors, the most common of which is the through hole resistor.

Types of Through Hole Resistors

There are two main types of through hole resistors - fixed resistors and adjustable resistors. Fixed resistors are non-adjustable resistors with a fixed resistance. These resistors are usually used for electrical circuits where the resistance value must remain constant. Adjustable resistors on the other hand, are designed to be manually adjusted to change the resistance. These resistors are useful for circuits that require the resistance to be adjustable.

Construction of Through Hole Resistors

Through hole resistors are made by creating a metal bridge across an insulating material. The materials used in creating the metal bridge range from carbon to metal films. The bridge is then connected to two metal leads, one of which is usually much longer than the other. This provides a convenient way of connecting the resistor to the circuit by inserting the leads into holes in a printed circuit board.

91J100E Application Field and Working Principle

91J100E is a type of through hole resistor. It is a fixed resistor with a resistance of 100Ω. It is mainly used in electronic circuits to provide a fixed resistance. It is also used in voltage divider circuits to divide the applied voltage.

The working principle of the 91J100E is relatively simple. The resistor works by creating a voltage drop across its components. This voltage drop is directly proportional to the current passing through it. By varying the amount of current that passes through the resistor, the applied voltage can be divided. As the current increases, the voltage drop across the resistor increases and the voltage at the other end of the resistor decreases.

Advantages of Through Hole Resistors

Through hole resistors provide several advantages to designers and circuit engineers. Firstly, they are cost efficient. They provide an inexpensive solution for incorporating resistance into a circuit. Additionally, they provide a large variety of resistance values with a single piece, as well as giving the flexibility to adjust the resistance value upon assembly. Lastly, they are easy to mount and do not require complex circuitry to interface with the board.

Conclusion

Through hole resistors are an essential component for any electronic circuit. They are relatively easy to use, reliable and inexpensive. The 91J100E is an example of a through hole resistor used in many electronic circuits. It is primarily used to provide a fixed resistance and divide the applied voltage in voltage divider circuits. Thus, providing an easy and cost-efficient way to incorporate resistors into any electronic circuit.
