Through Hole Resistors: H4118RBDA Application Field and Working Principle

Through hole resistors are a type of resistor material used in electronics and electrical engineering for a variety of purposes. This includes regulating current, signal conditioning, constructing networks, and more. Through hole resistors are vital components of many circuits, and can be found in numerous routing technology applications such as PCs, servers, and embedded systems. Over the years, technology advancements have enabled a number of different resistor designs, and today, the H4118RBDA through hole resistor is an extremely popular choice. In this article, we will discuss the application field and working principle of the H4118RBDA through hole resistor.

What Is the H4118RBDA Through Hole Resistor?

The H4118RBDA through hole resistor is a Through Hole resistor used for a variety of electronic and electrical engineering purposes. It is a general-purpose, ‘fixed’ resistor, capable of withstanding high temperatures and high voltages. The H4118RBDA has a cylindrical shape with two metal leads pre-assembled into the resistor body. This makes it ideal for cutting boards and automated surface mounting with other electronic components.

The H4118RBDA is a ‘compact-size’ through hole resistor which allows for easier connections and better space management. The resistor is rated for a maximum power dissipation of 0.35 watts and a capacitance of 12.1 pF. The resistor also features low DCR and inductance, allowing for fast switching and more reliable EMI/RFI protection.

H4118RBDA Application Field

The H4118RBDA through hole resistor has a wide range of applications. It is most commonly used for regulating current in circuits, signal conditioning, constructing networks, and forming inductive loads. The resistor is usually used in combination with other components such as capacitors, relays, and circuit breakers. Additionally, the H4118RBDA is suitable for a wide variety of industries including automotive, medical devices, consumer electronics, telecom, and more.

In automotive electronics, the H4118RBDA is often employed as a current limiting component in headlights and indicator lighting systems. The resistor is also used in medical device electronics, usually for providing accurate signal conditioning and current limiting for sensitive components such as imaging scanners and other medical equipment. The H4118RBDA is also commonly implemented in consumer electronics for forming filters, providing EMI/RFI protection, and other signal conditioning.

H4118RBDA Working Principle

The H4118RBDA through hole resistor works according to Ohm’s law. This law states that the current flowing through a resistor is proportional to the voltage applied across it. The current is also inversely proportional to the resistance. The H4118RBDA has a fixed resistance, meaning that the current through it is solely determined by the voltage applied. As the voltage increases, the current increases and vice versa.

The H4118RBDA resistor also allows for efficient heat dissipation. Heat is generated whenever current flows through a resistor. The resistor body serves as a ‘heat sink’, absorbing the excess heat and dissipating it into the surrounding environment. The H4118RBDA is designed to efficiently dissipate heat, allowing for better protection when compared to non-heat dissipation resistors.

In automotive applications, the H4118RBDA also provides additional protection against overvoltage and overcurrent. This protection is achieved by the resistor’s low Impedance. An Impedance is an electrical quantity which is equal to the impedance of a circuit, and is usually quoted in milliohms. The lower the Impedance, the better the resistors ability to withstand overvoltage and overcurrent conditions.

Conclusion

The H4118RBDA through hole resistor is a versatile, general-purpose resistor used for a wide variety of electrical engineering and electronic applications. It offers a high level of heat dissipation, low DCR, low inductance, and low Impedance, making it an excellent choice for current regulation, EMI/RFI protection, and signal conditioning. The H4118RBDA is used in many industries ranging from automotive, medical electronics, consumer electronics, and telecom.
