Through Hole Resistors: RN55D2002FRSL Application Field and Working Principle

Through hole resistors, also known as leaded resistors, are the most widely used type of resistor due to their low cost, ease of use, and excellent performance. The RN55D2002FRSL is a type of through hole resistor manufactured by the National Semiconductor Corporation. It is a high-power, low-cost, through hole resistor with a power rating of 25W and an operating temperature range of -55 °C to +150 °C.The RN55D2002FRSL is typically used in applications demanding a heavy current overload, such as high-power LED lighting, motor control, power supplies, and so on. The component’s exceptionally low and stable temperature coefficient of resistance ensures consistent performance even in harsh environments. In addition, the component is highly cost-effective as it offers a minimal per-unit cost when compared to other through hole resistors.The working principle of a through hole resistor like the RN55D2002FRSL is quite simple and straightforward. When an electrical current passes through the resistor, the metal material of the resistor resists the flow of current, causing friction that creates a voltage drop. This voltage drop is then translated into a resistance value. The resistance value of the component is determined by its characteristics, including its size, material, shape, and construction.The construction of the RN55D2002FRSL is designed to resist heavy currents, with its metal oxide layer providing additional insulation and its gold-plated copper terminals securely gripping the resistor leads for an improved electrical connection. Its lead centers are made of high-temperature materials, providing superior heat dissipation and an extended operating temperature range. It also has a unique construction, allowing it to withstand even harsh environments without any damage.In terms of safety, the RN55D2002FRSL is rated to a maximum voltage of 50 volts and a maximum current of 25 amps, making it suitable for a variety of applications. By providing a stable voltage and current output, the component helps to ensure safe operation at all times. Overall, the RN55D2002FRSL is an excellent choice for high-power applications that require a low-cost, reliable, and high-performance through hole resistor. Its low temperature coefficient of resistance and excellent construction make it an ideal choice for heavy-duty applications, providing users with consistency and reliability. With its extensive temperature range and heavy current rating, the RN55D2002FRSL ensures safe operation even in the most demanding environments.
