Through hole resistors are a type of resistors which are designed to be mounted with their body passing through a hole in a printed circuit board or other substrate. The H4274KBCA is a through hole resistor designed to provide superior performance in a wide range of applications. In this article, we will discuss the application field and working principle of the H4274KBCA.

H4274KBCA Application Field

The H4274KBCA through hole resistor is a standard, high-reliability device designed for resistive applications such as voltage dividers, attenuators, amplifiers, and current limiting circuits. It is capable of handling higher power than many other types of resistors and is particularly well suited for high-temperature and high-vibration environments. Additionally, the H4274KBCA is optimized for applications with rising temperatures, temperature cycling, and shock and vibration, making it ideal for military, aerospace, automotive, and other harsh environments.

The H4274KBCA’s flattened body design provides superior thermal performance, allowing it to be used in high-power and high-temperature applications. Additionally, its axial leads provide a wide range of leadstacking options, making it ideal for tight spaces. It is also rugged and vibration-resistant due to its nickel-plated package.

H4274KBCA Working Principle

The H4274KBCA through hole resistor is based on the principle of resistance. It is made up of a ceramic body, a resistance element, and metal endings. The resistance element is usually formed by depositing a conductive material on a ceramic substrate, and the metal endings are used to connect the resistor to the circuit. The resistor is then sealed inside a corrosion resistant enclosure for protection.

When a voltage is applied across the resistor, current flows through the resistance element and the applied voltage is reduced by a certain amount. The amount of voltage reduction is determined by the resistance of the resistor. The power dissipated by the resistor is determined by the product of the current and the voltage applied.

In most cases, the resistance of the H4274KBCA through hole resistor will remain constant over a range of voltages and currents. This makes it suitable for applications where the amount of voltage reduction needs to remain constant. Additionally, since the resistor is designed for high temperatures, it can safely handle large voltages and currents without damage.

Conclusion

The H4274KBCA is a through hole resistor designed for high temperature, high vibration and tight space environments. It has a flattened body design which provides superior thermal performance and axial leads which provide a wide range of leadstacking options. It is also vibration resistant and capable of handling higher power than many other types of resistors. The H4274KBCA is based on the principle of resistance and operates by reducing the voltage applied across its terminals by a certain amount determined by its resistance. This makes it ideal for resistance-based applications such as voltage dividers, attenuators, amplifiers, and current limiting circuits.
