Through Hole Resistors

Through hole resistors, also known as axial resistors, are a type of resistor that is mounted directly into a printed circuit board (PCB) and attached to the board by soldering. Due to their versatility, they are one of the most commonly used resistors within the electronics industry. The H4267RBYA is an example of a through hole resistor that is widely used for a variety of applications.

H4267RBYA Application Field and Working Principle

The H4267RBYA is a metal-oxide-film resistor that is typically used for general applications such as pulse circuits, amplifiers, voltage regulators, and audio systems. It is most commonly available in the standard 4-pin TO-220 package, and is designed for high power and high frequency performance in both AC and DC circuits. The H4267RBYA has an operating temperature range of -55°C to 155°C and a maximum power rating of 400W.

In terms of its working principle, the H4267RBYA has a resistance element that is made of metal oxide film. This element is formed using a vacuum evaporation process and is then placed between two ends - each end of the element has one lead wire embedded in a ceramic substrate. When current flows through the resistor, the charged particles of the metal oxide film collide with each other and generate heat.

The amount of heat generated is proportional to the amount of current that is passing through the resistor, and this heat is dissipated through the ceramic substrate into the air. This heat transfer converts the electrical energy of the current into thermal energy, resulting in a decrease in the current flow. The amount of current flow that has been reduced is proportional to the resistance of the resistor.

The H4267RBYA is also equipped with an internal heat-sink to provide additional heat dissipation. This heat-sink dissipates the heat away from the resistor element, ensuring that its temperature stays within the safe operating range. By keeping the resistor cool, it is able to operate at higher temperatures for longer periods of time with improved reliability.

The H4267RBYA is a versatile and reliable component that is perfect for any application that requires reliable current control and efficient temperature management. Its robust structure ensures reliable performance in a wide range of operating conditions and operating temperatures. With its wide range of applications, the H4267RBYA is the perfect choice for any application that requires a durable and reliable resistor.
