Chassis Mount Resistors combine the electrical and mechanical characteristics of a resistor with a mounting system, which enable them to be integrated into an electrical chassis design. The RER60FR249RC02 is a Chassis Mount Resistor designed for use in high-power applications such as those found in lighting, industrial and automotive. This type of resistor has a wide range of application in many industries.The RER60FR249RC02 is a film type chassis mount resistor designed for high heat dissipation in extreme temperature environments. Its low thermal resistance makes it ideal for applications that require low thermal rise under load. The resistor also has a high frequency response, allowing it to be used in applications that need fast response times. This resistor also has a better noise rejection properties compared to other types of film resistors.The RER60FR249RC02 has a zero resistance below a certain temperature and a maximum of 3 ohms at 150 degrees Celsius. The maximum working temperature is 125 degrees Celsius, and the resistor is constructed with 0.5 mm thick film and is ideal for use in applications where long life is needed. The resistor is also designed with a layer of ultra-fine gold wire wound around the resistance element, which provides excellent environmental protection.The working principle of the RER60FR249RC02 is simple; it works by dissipating heat and controlling electrical current. The resistor is designed to act as a “hot spot”, absorbing heat as electricity passes through it. This heat is then transferred to the environment, allowing it to dissipate. The amount of energy dissipated by the resistor depends on the current and voltage passing through it.The RER60FR249RC02 has a variety of applications, from lighting to industrial control. It is also suitable for power electronic components such as DC-DC converters, inverters, and ESD protection. In automotive applications, it is often used in spark plug leads and as wiring protection for power supplies. It can also be used in high-power electronic ballasts and as an over-temperature protection element.In summary, the RER60FR249RC02 is a Chassis Mount Resistor designed for high-power applications and is suitable for a variety of applications. With its low thermal resistance and fast response times, it is ideal for applications that require extreme temperatures and fast response times. Its unique combination of electrical and mechanical characteristics provides excellent environmental protection, making it well-suited for long-term performance in harsh environments.The specific data is subject to PDF, and the above content is for reference
