RNF12FTD2M87

Through Hole Resistors come in many shapes, sizes and types, but the RNF12FTD2M87 stands out as a highly reliable and versatile variant. Generally speaking, the purpose of a Through Hole Resistor is to control electric current and to create a stable and secure environment in electronic circuitry. Specifically, the RNF12FTD2M87 is a carbon resistor with a fixed, non adjustable value of 47K Ohms. The resistance value is displayed as a colored ring on the body of the resistor and the body is made of glass epoxy (FR4), which provides excellent environmental stability and mechanical properties.

The key characteristics of the RNF12FTD2M87 make it suitable for a variety of applications, ranging from computer motherboards and consumer electronics to telecom equipment and instrumentation. Its high wattage rating (8W) means it can handle a higher power load than many Through Hole Resistors, making it suitable for use in power-intensive tasks. The resistor’s high temperature coefficient (TCR) also makes it suitable for applications in which temperature variations are a factor, as it will remain stable and reliable under different conditions. Furthermore, its high accuracy rating (1%) ensures that the value of the resistor remains within its stated tolerance, making it suitable for use in precision circuits.

The working principle of the RNF12FTD2M87 is based on the fact that when a voltage is applied across a resistor, an electric current will flow through it. The greater the voltage, the greater the electric current. When the voltage reaches a certain level, known as the rated power dissipation, the resistor will start to heat up, and this will reduce its resistance, causing the current to drop. As the resistor becomes hotter, its resistance will continue to decrease until it reaches a point where the current stops flowing.

To maintain the correct resistance, a cooling system is necessary. The RNF12FTD2M87 uses a natural cooling system based on convection, meaning air is used to carry heat away from the resistor and into the environment. For added reliability, the resistor also has a built-in thermistor, which monitors the temperature of the component and adjusts the resistance accordingly to keep the temperature within its specified range.

The RNF12FTD2M87 through hole resistor is a long-lasting, dependable and versatile device with a wide range of applications. It’s an excellent choice for any type of electronic circuit, from computer motherboards to instrumentation and telecom equipment. Its high wattage rating, high temperature coefficient, and high accuracy rating make it suitable for numerous tasks, ensuring a stable and secure environment for various electronic applications.
