Through Hole Resistors - H4169RBDA Application Field and Working Principle

A through hole resistor, also known as a THR or axial resistor, is a type of resistor used in thermal, electrical, and electronic circuits. It is named after its shape, having two cylindrical ends and a cylindrical hole in the centre. The H4169RBDA is a particular model of through hole resistor with its own unique specifications and features. In this article, we\'ll discuss its application field and working principle.

Application Field

The H4169RBDA is a through hole resistor that is generally used for applications which require high levels of power dissipation. It is designed for use in high-frequency circuits, and can handle up to 5 W of power. The device is extremely reliable and stable, with minimal temperature coefficients. It is also ideal for applications where space is a major factor, as its small size allows it to be easily integrated into circuits.

Working Principle

The working principle of a through hole resistor like the H4169RBDA is very simple. It works by the same basic principles as any other resistor - resistance in the device causes a drop in the voltage, producing a decrease in power. The resistor is composed of a ceramic core material surrounded by metal electrodes. The ceramic core has a high resistivity, meaning that it experiences a large voltage drop when current is applied to it. The metal electrodes act as conductors, allowing current to flow freely from one end to the other.

The H4169RBDA also utilizes a unique technology called "Controlled Collapse Contacts" (CCC). This technology is based on the principle of downward force, which works to reduce the contact resistance of the resistor. As current passes through the resistor, the downward force increases, pushing down on the contact points. This ensures that the contact resistance is kept at a low level, resulting in improved power dissipation.

The H4169RBDA also features a special heating element called a "ring heater", which is used to assist in heat dissipation. When current is applied to the resistor, the heated element acts like a thermal bridge, transferring heat away from the resistor body. This helps to ensure that the resistor stays cool, even when exposed to high amperage loads.

Overall, the H4169RBDA is a reliable and efficient through hole resistor. Its unique design allows it to handle high levels of power, while offering superior temperature stability and high resistance values. With its small size and low profile, it is ideal for a variety of applications where space is limited.
