RER65FR301MC02

Chassis mount resistors are a type of passive electronic component that serves to regulate current in a circuit and to protect components from damage caused by high voltage or current overloads. The RER65FR301MC02 is one of the most popular chassis mount resistors on the market. This article will explore the application field and working principle of the RER65FR301MC02.

The RER65FR301MC02 is specifically designed for high power applications that require great accuracy and stability, such as AC/DC switching power supplies, motor drives, LED lights, and integrated control systems. It is a low inductive device, constructed of four parallel metal oxide (MOX) chips, ensuring an efficient heat dissipation and improved audio performance. The RER65FR301MC02 is capable of dissipating up to 140 mW of power per chip, making it one of the most powerful available chassis mount resistors on the market. It has a wide operating temperature range, from -55°C to +125°C, and a wide dynamic range, from 1mΩ to 5MΩ.

The RER65FR301MC02 also boasts an impressive accuracy of ±0.15% and a tolerance of ±5%. Its lead-free terminations and RoHS compliant package make the RER65FR301MC02 suitable for a variety of industrial environments. It is also highly reliable, with a 10-year product life expectancy and a surge power rating of 2 watts.

The RER65FR301MC02 has two primary types of working principles: balanced resistance and power dissipation. The balanced resistance working principle derives from the fact that each of the four MOX chips have identical electrical properties. This means that the RER65FR301MC02 is not affected by external temperature changes or fluctuations, ensuring greater stability and accuracy of the device. The second principle is power dissipation, which is how the RER65FR301MC02 is able to dissipate high wattages within a small package. This is achieved using a thermal conductive coating on the lead wires of the device to remove heat away from the source.

In conclusion, the RER65FR301MC02 is an highly reliable and accurate chassis mount resistor designed for high-power applications. Its low inductive structure, wide operating temperature range, accuracy of ±0.15%, and 10-year product life expectancy make it a highly attractive device for industrial use. Its two primary types of working principles, balanced resistance and power dissipation, ensure it is able to adequately dissipate power and remain accurate over time.
