Through Hole Resistors

Through-hole resistors are commonly used for a variety of tasks, including controlling voltage and current levels, precision timing, and maintaining circuit continuity. The RN55D2712FB14 through hole resistor is a high-performance component utilized for a range of applications. This article outlines the RN55D2712FB14’s application field and working principle.

Application Field

The RN55D2712FB14 is designed for general-purpose use in power circuits, such as with power supplies for computers, servers, office machines, industrial automation systems, and telecom equipment. The resistor is versatile and suitable for electronic projects such as DC-DC converters, audio amplifiers, and motor controls.

Due to its high operating temperature and tolerance rating, the RN55D2712FB14 has a particularly high power dissipation rating and can be utilized for applications ranging from 100 to 250 Watts. The high reliability of the component means it is well suited for circuits operating in poor environmental conditions, such as those exposed to extreme temperatures, vibration, shock, humidity, or electromagnetic interference.

Working Principle

The RN55D2712FB14 is a carbon-film resistor with a fixed resistance value of 2.7 Ohms and a max. dissipation rating of 11 Watts. It operates in both AC and DC applications and is suitable for low-level audio signal circuits as well as high-power circuits.

The resistor’s operation is based on Ohm’s Law, which states that voltage is equal to the current times the resistance. That means that the resistor reduces the voltage and current levels which pass through it, and the greater the resistance, the greater the voltage and current drop. The current flowing through the resistor is proportional to the voltage applied to it, and the power dissipated by the resistor depends upon both.

In the RN55D2712FB14, the resistance is achieved by a spiral carbon film which is wrapped around a core and short-circuited both ends. The maximum power, or wattage, which the resistor can dissipate is determined by its physical size, and the component’s size and shape is designed to achieve the optimal heat dissipation for the wattage rating of the resistor.

The RN55D2712FB14 is designed to withstand temperatures between -55°C and 155°C, making it suitable for both indoor and outdoor use, and its tolerance rating of ±5% provides assurance that the resistor’s actual resistance is within close tolerances of its nominal value.

Conclusion

The RN55D2712FB14 through-hole resistor is designed for general-purpose use in power circuits, and is suitable for a range of applications from DC-DC converters and audio amplifiers, to motor controls and precision timing. This carbon-film resistor has a fixed resistance of 2.7 Ohms and a tolerances rating of ±5%, and it operates within a temperature range of -55°C to 155°C.
