43F4K0E Through Hole Resistors: Application Field and Working Principle

Through hole resistors are often used in electrical circuits to limit current or to divide voltages. This article explains the application field and working principle of 43F4K0E through hole resistors.

General Introduction to Through Hole Resistor

Through hole resistors, as the name implies, use a hole drilled into a printed circuit board (PCB) as their mounting method. They are usually cylindrical in shape and can range from 0.5 mm to 25 mm in diameter and from 1 mm to 50 mm in length. They are the most popular type of resistor used in PCBs due to their easy installation and relatively low costs.In addition, metal film resistors, carbon film resistors, and metal oxide resistors are available on the market, with the latter two being cheaper. The resistance of a through hole resistor can vary from 0.5 ohm to 200 kOhm.

Application Field of 43F4K0E Through Hole Resistor

The 43F4K0E is a through hole resistor with a resistance of 4.3 kOhm. It is a popular choice for voltage division, current limiting, and power supply regulation applications. As the resistance is relatively low, this component is often used in circuits that require a moderate current flow.For example, in power supplies, 43F4K0E resistors can be used to divide the input voltage into voltages suitable for lower-voltage components. Similarly, in sensors, these resistors can be used to divide the output voltage so that it can be read by an analog-to-digital converter (ADC). In addition, they can also be used in DC motor speed control applications.

Working Principle of 43F4K0E Through Hole Resistor

A 43F4K0E through hole resistor works in a very simple way. When a current is applied to the two terminals of the resistor, a voltage drop occurs across the device due to its resistance. This voltage drop can be calculated by Ohm’s law, which states that the voltage drop is equal to the current multiplied by the resistance.Since the resistance of the 43F4K0E is fixed, the voltage drop will be the same for a given amount of current. This makes it useful for applications where a constant voltage drop is required, such as voltage division or current limiting. The resistance of the resistor can be adjusted by changing its physical dimensions, such as its length or diameter.

Conclusion

In conclusion, the 43F4K0E through hole resistor is a popular choice for voltage division, current limiting, and power supply regulation applications. Its resistance is fixed and can be adjusted by changing its physical dimensions. The current flowing through it produces a voltage drop across the resistor which can be used for a variety of purposes.
