Through Hole Resistors play a vital role in many industries including electrical and electronic engineering, automotive and aerospace. The H839RFYA is an example of such. As a through-hole resistor, its application fields and working principle will be discussed in this article.

Application Fields of H839RFYA

H839RFYA through-hole resistors are often seen in feedback circuits, audio equipment, automotive, environmental monitoring, home appliance, agriculture, medical devices, battery management circuits and industrial control systems. It is widely used for supplying power, voltage balancing, and noise reduction. As it is constructed as a through-hole device, it can be reliably mounted to desoldered printed circuit boards.

The resistor is available in 0.5W, 1W, 2W and 4W power ratings, which make it exceptionally suitable for use on circuit boards with high voltage and current levels. With excellent high frequency performance and power dissipation, H839RFYA can also be used in replacement of conventional carbon film resistors with a much better reliability than them.

Additionally, the resistor also enjoys a IP67 enclosed waterproof rating, allowing it to protect more sensitive components against dust, water, and other contaminants.

Working Principle of H839RFYA

H839RFYA through-hole resistors employ temperature coefficient technology to convert input voltage and current into a resistive value. Basically, when an electrical current passes through the device, the resistive material causes a drop in the voltage and current levels as it passes through. This voltage or current drop is known as “resistance” or “impedance”.

This means that when an electric current is input into the resistor, the resistor will convert these current values into a resistive value that can be used to reduce voltage or current levels. This conversion is made possible through the electrical properties of the material itself, which is usually a type of quartz-based material.

In order to accurately measure the required value of resistance, the resistor must be precision engineered and calibrated. The resistor is then given a resistance rating, which is the ratio of the resistance to input or output current. By controlling this rating, the resistor can be used to create an effective current conversion or voltage reduction.

An advantage of H839RFYA is that it can also be used for reverse current and voltage converters, allowing the device to be used to increase or reduce currents and voltages. This is extremely useful for creating adjustable and user-controlled electrical systems.

Conclusion

Through hole resistors, like H839RFYA, play an important role in many industries. Its application fields include feedback circuits, audio equipment, automotive, environmental monitoring, home appliance, agriculture, medical devices, battery management circuits and industrial control systems. Moreover, the resistor is also constructed with temperature coefficient technology to convert input voltage and current into a resistive value. With excellent high frequency performance and power dissipation, H839RFYA can be used as a reliable replacement of conventional carbon film resistors.
