Through Hole ResistorsApplication field and Working Principle Of HHV100FT-73-100K

Through hole resistors are resistors that are placed and soldered on the surface of PCB through holes. They are also called leaded resistors and axial resistors. The main purpose of a through hole resistor is to regulate the current in an electric circuit. This type of resistor is most commonly used in simple circuits like resistive voltage dividers.

HHV100FT-73-100K is a through hole resistor with a rated power of 100 mW and a resistance value of 100 kΩ. It is designed with a control performance of ± 5%, temperature coefficient of ±100 ppm/℃ and voltage coefficient of ± 10 ppm/V. It has high power rating and low temperature coefficient, ensuring the accuracy of electrical components.

Application Field

Through hole resistors like HHV100FT-73-100K can be widely used in various fields, such as digital circuit, audio / video circuit, automotive circuit and inductive circuit. Generally speaking, they can be used in any circuit with relatively low power and resistance values. In digital circuits, through hole resistors are typically used to regulate the flow of current through a signal line, or to prevent certain components from being damaged by excess current.

In audio / video circuits, through hole resistors can be used to provide protection for sensitive components and to set the gain of an audio amplifier. Other applications include providing a stable voltage reference for analog to digital conversion, as well as providing current limiting to protect devices from over-current conditions.

Through hole resistors are also used in inductive circuits because they can provide the necessary resistance to make a certain inductor function properly. They can also be used to provide a voltage drop in series circuits, or to provide a current path for a short circuit.

Working Principle

The working principle of a through hole resistor mainly involves three concepts: resistance, Ohm’s Law, and voltage drop. Resistance is the opposition of a substance to the flow of current within it, while Ohm\'s Law states that the voltage between two points is directly related to the current going through it. When electrical current passes through a resistor, the voltage across the resistor will be lower than at the input terminal.

This is because some of the energy has been lost to the resistor slab. The amount of energy lost depends on the resistance of the resistor and the amount of current through it. By adjusting the resistance of the through hole resistor, one can regulate the voltage drop across the resistor, allowing it to be used in a variety of different applications.

Conclusion

Through hole resistors are very versatile components that can be used in a variety of different applications. HHV100FT-73-100K is an example of such a resistor that can be used for digital circuits, audio / video circuits, automotive circuits, inductive circuits, and more. These resistors function by regulating the voltage and current, and this is achieved through the principles of Ohm’s law and voltage drops.
