Resistors are electronic components used in circuits to control current flow and voltage levels, and they come in two basic types: through-hole resistors and surface mount resistors. The RC12KB220R is an industrial-grade, through-hole resistor. In this article, we will discuss the application field and working principle of the RC12KB220R.

Functionality

The RC12KB220R is a high-precision, through-hole resistor that provides accurate and reliable stability and performance in elevated temperatures and exposures to high vibration. The chip is designed for use in military, industrial, aerospace and commercial applications. It is also designed for use in cases where there is potential incorrect application due to unstable circuits, high concentrations of power application or extreme physical and chemical exposure. Its metalized construction enables improved temperature and vibration stability.

Physical Properties

Physical properties of the RC12KB220R include a rated voltage of 220V and a 25mΩ resistance. With dimensions of 12.7mm x 6.2mm x 11.4mm, it is a relatively small component. The chip is designed to dissipate heat using a power rating of 50mW and an operating temperature range of -55°C to +150°C. Furthermore, the component\'s case material is made of copper which ensures effective heat dissipation. It also features a tolerance of ±6%.

Performance

The RC12KB220R is capable of providing an accurate resistance even at elevated temperatures, providing control of both current and voltage levels in the circuit. Its thermal characteristics enable the resistor to maintain its physical properties over an operating temperature range of -55°C to 150°C with minimal changes in resistance or drift in temperature coefficient. Additionally, the copper jacket around the resistor ensures less heat loss, improving device performance.

Working Principle

The working principle of the RC12KB220R is based on the utilization of electron mobility along a conductor in order to resist current flow. When the electron mobility is increased, the resistance is increased, and when it is decreased, the resistance is decreased. As electrical current passes through the wire of the RC12KB220R, the resistivity of the wire affects the flow of current. The greater the resistivity, the greater the resistance and the lower the current. As the current is regulated by the voltage and current present in the circuit, the electron mobility is able to modify the current flow when necessary.

Conclusion

The RC12KB220R is a through-hole resistor used in military, industrial, aerospace and commercial applications. It provides accurate and reliable performance characteristics and is designed to handle extended exposure to high temperatures and vibration. The physical properties, functionality and working principle of the RC12KB220R enable the chip to improve the performance of electronic circuits and make them more reliable.
