Chassis mount resistors are a range of resistors specially for mounting either directly or in a cavity within a housing or chassis. These types of resistors offer a range of performance and features that aid their mounting within a larger system, such as dust and splash proofing, protecting components from extreme temperatures and even mounting of them on a chassis without requiring additional hardware. The RER70F66R5RC02 is one such type of chassis mount resistor and its application field and working principle are explored further in this article.
The RER70F66R5RC02 is a type of chassis mount resistor suitable for applications which require ratings above the standard film resistor’s power dissipations. It is specifically suitable for applications where high power is required or where space is a premium. The resistor is designed to fit a standard 5mm hole, meaning it is possible to mount it without the need for new or additional hardware.
In terms of its electrical characteristics, the RER70F66R5RC02 has a power rating of 70W, with a resistance range of 0.1Ω to 100KΩ. The resistor has a tolerance of ±0.1%, a working voltage of 600V, and a thermal time constant of 0.5 s. Furthermore, the resistor is rated for an extreme operating temperature range of -65°C to 175°C, making it a suitable choice for both hot and cold environments. Lastly, this type of resistor offers a flat terminal design, further aiding its ready-to-fit into almost any chassis.
How the RER70F66R5RC02 works is simple. As an electrical component, it allows a certain amount of current to flow through it, and this is directly proportional to its resistance rating. The lower the resistance rating, the more current that will be able to flow, and vice versa. The voltage passed through the resistor will remain constant, and the amount of power dissipated by the resistor is determined by the amount of current that is allowed to flow through it.
The RER70F66R5RC02 achieves its level of performance by incorporating an advanced temperature compensation mechanism. This mechanism is able to adjust the resistance of the resistor in order to compensate for changes in temperature, and also compensates for any voltage fluctuations. This ensures that the resistor is not damaged due to excessive heat, and provides a consistent performance across a variety of environments.
The RER70F66R5RC02 is a reliable and durable chassis mount resistor, suitable for a wide range of applications that require power ratings above what is available with regular film resistors. Its form factor and advanced temperature compensation mechanism make it an ideal choice for use in most Chassis Mount systems. Furthermore, its power rating and temperature range make it outstanding choice for applications which demand some of the highest levels of reliability and performance.
