It is common knowledge that Chassis Mount Resistors are used in many industries, including consumer electronics, HVAC systems, automotive and aerospace components, and medical equipment. The C300KR20 is a unique type of chassis mount resistor that has been specifically designed for use in high temperature or high-performance applications. It is a robust, versatile design that can handle up to 125°C and is UL/CSA approved.

The C300KR20 is a surface-mount or through-hole metal-oxide-film resistor with a standard 300 watt power rating. The resistors feature four separate contact points, which are commonly used to connect to the board. They also have an electrical dielectric rating of 250 volts, and an insulation thickness rating of 0.1mm. This helps to ensure reliable operation in even the most difficult temperature and application environments.

The working principle of the C300KR20 is quite simple. When a current is applied to the resistor, the contacts will act as a conductor, forming an electrical circuit. This will cause the resistance between the two contacts to decrease, thereby reducing the amount of power that is dissipated into the board. The resistance will then linearly increase as the temperature increases. This helps to maintain consistent performance over a wide range of application conditions.

The versatility of the C300KR20 also makes it well suited for a wide range of applications. It is commonly used in power supplies, automotive and medical electronics, and industrial electronic systems. The resistor is suitable for use in extended temperature ranges as well, since it can withstand up to 125°C. In addition, the C300KR20 is UL/CSA approved, which means it is compliant with all necessary safety standards.

In summary, the C300KR20 is a reliable, versatile chassis mount resistor that is UL/CSA approved and suitable for use in extended temperature ranges. Its simple working principle makes it easy to install and maintain, and its robust design ensures consistent performance even in the most demanding applications. As such, the C300KR20 is an ideal choice for any high power, high temperature, or high-performance applications.
