Through Hole Resistors

Resistors are an integral part of electronics, especially for building complex circuits. Through hole resistors are one type of device for building such circuits. They are an excellent choice for anyone wanting to build a secure, reliable, and long-lasting electrical circuit. This article discusses one particular type of through hole resistor, the RNV14FAL820K, and its application fields and working principles.

What is a Through Hole Resistor?

A through hole resistor is a type of resistor that is mounted and retained on a printed circuit board by inserting its two ends, known as leads, through the pre-drilled holes of the board and soldering them to the board\'s conducting tracks. This type of resistors are usually made of ceramic or metal-oxide layers that are formed into a cylindrical shape, with leads welded to both sides. They act as direct, fixed measurement elements, which can either drop the voltage of a certain current, or prevent it from flowing.

Application Fields of RNV14FAL820K

The RNV14FAL820K through hole resistor is a metal-oxide type resistor that is most often used for power dissipation as well as current limitation applications. It is commonly found in the automobile and aerospace industries, as well as in industrial applications. It is particularly designed for applications that require high power operation and resistance values over a wide temperature range.

Working Principle of RNV14FAL820K

The working principle of the RNV14FAL820K is simple. It is designed to limit the current flowing through a circuit by lowering the voltage across it. The resistor is composed of two metal-oxide layers, which are the positive and negative layers separated by an insulating layer. These layers are typically made of aluminium oxide, ruthenium oxide, beryllium oxide, or other materials with high electrical resistivity. When a voltage is applied across the resistor, an electrical current will flow through it. The resistance value of the device is determined by the material used and the geometry of the device. The current flowing through the resistor is inversely proportional to the resistance of the device, meaning that if the device’s resistance is increased, the current decreases. This makes the RNV14FAL820K especially suitable for applications that require high power and precise current control.

Conclusion

Through hole resistors are an important type of resistor for building secure and reliable circuits. The RNV14FAL820K specifically, is a metal-oxide type resistor that is used for high power operations as well as current limitation applications. Its working principle is simple: it is designed to limit the current flowing through a circuit by lowering the voltage across it. By understanding its application fields and working principles, engineers can quickly and accurately design electronic circuits with the RNV14FAL820K.
