Through Hole Resistors: H42K37DYA Application Field and Working Principles

Through hole resistors, also known as axial lead resistors, have been used in a wide range of applications for decades. The H42K37DYA is one of the flagship models of this resistor type.

What is the H42K37DYA?

The H42K37DYA is an axial lead resistor, which is typically composed of a wire core with a two-strand lead wire attached to each end, insulated by a paper or plastic tube. It has a resistance value of 4.7kΩ ± 2%. This resistor is designed to dissipate heat generated while allowing for current flow.

What Are the Application Fields?

The primary application fields of this resistor include power supply, electrical engineering, electronic engineering, integrated circuit, telecom engineering, mechanical engineering, and automobile industry. Generally speaking, it is mainly used in power electronics, but can also be applied in other areas that require higher current-carrying capacity, such as radio communication, TV receivers, and computers.

How Does it Work?

The resistance of the wire determines the amount of current that can be conducted through it. The longer the wire or the higher the resistance, the less current that will flow. The H42K37DYA, being 2% more resistant than its rated resistance of 4.7kΩ, will, in general, allow for a smaller current flow. In addition, its paper or plastic insulation helps to suppress high voltage transients, enabling the resistor to handle higher voltages without damage.

Main Benefits

Axial lead resistors, of which the H42K37DYA is one of the most popular models, boast a number of benefits that make them ideal for a variety of applications. Their design allows for easy mounting in small spaces and also allows for components to be “stacked” together when necessary. Axial lead resistors also offer better corrosion resistance and improved thermal performance over other resistor types.

The H42K37DYA, in particular, has a wide range of advantages, including higher power dissipation, better structural strength, excellent electrical insulation, and superior temperature and noise resistance compared to other resistors. Its 4.7kΩ resistance level offers a broad range of applications, making it suitable for a variety of needs.

Conclusion

The advantages of through hole resistors, such as the H42K37DYA, make them ideal for a multitude of devices and applications. Its high power dissipation and superior temperature and noise resistance makes it the perfect choice for any situation requiring reliable performance. In addition, its simple design allows for easy mounting and stacking. With such a wide range of benefits, it is no surprise that the H42K37DYA is one of the most popular axial lead resistors on the market.
