Through hole resistors are an essential aspect of a wide variety of circuit applications. The RN55D2215FRE6 is just one type of through hole resistor in existence. These resistors fit comfortably into printed circuit boards (PCBs) and make use of axial leads, making this type of resistor quite useful for a number of applications.

Applications

The RN55D2215FRE6 is typically used for applications such as signal, power, and data processing. It is often found in common electronic items, including audio systems, computer motherboards, amplifiers, instruments, and more. The resistor is rated for a maximum power of 2 watts and has a resistance range of 22 to 15K ohms and a tolerance of ±2%. This makes the resistor suitable for most audio applications.

The power rating of the resistor warrants its use in power supply applications and other power related projects. The resistor is also suitable for DC/DC converters, power transistors, motor control, and other power applications. The resistor also features a small size, making it ideal for miniaturized electronic designs, including simple battery-powered designs.

Working Principle

A through hole resistor consists of a resistive material wrapped around a spool. The resistor is then encased in an epoxy cylinder that is inserted into a cylindrical hole in the PCB. The resistor is then soldered into the board.

The RN55D2215FRE6 features axial lead construction, meaning that its leads come from both ends of the resistor. The two leads are long enough to be pushed through the PCB and the resistor body is small enough to fit into the cylindrical hole. The leads are then bent under the resistor body and soldered into the printed circuit board.

This type of resistor works by providing a resistive path for current to flow. The resistor works by turning the current into heat and dissipating it away from the circuit. This is necessary to protect the components in the circuit from being damaged by excessive levels of current.

Final Thoughts

The RN55D221FRE6 is an example of a through hole resistor used for a variety of applications. It features axial lead construction, a resistance range of 22-15K ohms, and a power rating of 2 watts. The resistor is suitable for signal, power, and data processing applications, particularly for power supply applications and DC/DC converters. The resistor also features a small size and can be soldered onto a printed circuit board. Furthermore, the resistor works by providing a resistive path for current and turning it into heat before dissipating it away from the circuit.
