Through Hole Resistors are a very versatile type of resistor with wide applications in electronic circuits. The CA0002470R0KS73 is a classic example, and its features and working principles will be examined in this article.

The CA0002470R0KS73 is a Through Hole Resistor that provides a preset, fixed current limiting at temperatures ranging from -55 to +125°C. It is designed with two fixed leads extending through a round ceramic insulator. That insulating material provides an electrically non-conductive barrier between the leads, isolating them from the surrounding environment, and makes it suitable for connecting multiple components. A special signal processing circuit is integrated within the resistor to protect it against overload and incorrect connections.

The application field of the CA0002470R0KS73 is mainly in high-temperature power supplies. It is suitable for a variety of applications, from systems with higher-amperage loads such as electric ovens and furnaces, to low-amperage applications like solar panels and charging circuits. Its low thermal resistance and inherent current-limiting make it also suitable for automotive, lighting, and even audio and communications applications. The CA0002470R0KS73 is rated for maximum power dissipation up to 500 watts.

The working principle of the CA0002470R0KS73 is based on the phenomenon of electromigration. Electromigration is the process whereby electrons move through a conducting material under an applied electrical field. When a voltage is applied across the resistor, electrons are attracted to the positive terminal and their movement generate an electric field within the resistor. This electric field creates an opposition to the applied voltage, thus limiting the current through the resistor.

The CA0002470R0KS73 is designed and tested according to UL94 standard specifications. It is fabricated with a special material formulation, featuring a high-density composite of carbon and Nickel to ensure its stable performance even when exposed to high temperatures and high-powered electrical signals. The resistor is also equipped with several safety features such as built-in over-voltage protection, reverse polarity protection, and other safety measures.

In summary, the CA0002470R0KS73 is a Through Hole Resistor with several remarkable features and a wide application field. Its high power rating and current-limiting abilities make it a suitable choice for many power applications, such as electric ovens, automotive lighting, and solar panels. Its robust construction and UL94 certification make it the ideal choice for applications with extreme and hazardous conditions.
