Chassis Mount Resistors
Chassis mount resistors refer to resistors mounted in enclosures or in frames which serve to protect them from the environment. This type of resistor is typically found either under the hood of an automobile or in industrial equipment, and are designed to dissipate significant amounts of energy when subjected to high levels of current. The RER45F4990PCSL is an example of a chassis mount resistor. This type of resistor is designed to handle large power loads for industrial applications and has an operating temperature range of -55 to +150 degrees Celsius.
The RER45F4990PCSL is a thick film, surface mount, four leaded, chip resistor with an insulation layer between the body material and the metal insert. It offers good electrical characteristics in 50,000 voltage, 0.2 watt rating with power derating above 25 degrees Celsius. This resistor is ideal for applications which require high electrical performance, overload protection, and heat resistance. In addition to the RER45F4990PCSL, there are a wide variety of chassis mount resistors available from various manufacturers in a variety of sizes, specifications, and ratings.
RER45F4990PCSL chassis mount resistors are used in a variety of applications, including high-temperature, high-power, and overload protection applications. In automotive applications, the resistor is used for high-temperature control and protection, as well as for overload protection. In industrial applications, it is often used as a circuit breaker for short-circuiting and as a current limiting device for protection against overloads. The resistor is also used in solar systems, for power protection, and for motor control.
The working principle of the RER45F4990PCSL is based on the use of thick film technology. Thick film technology involves printing a metal and insulating layer onto a supporting substrate material. The metal-insulated layers form the resistance elements on which the resistors are formed. The substrate material is then die-cut, mounted, and wired into a circuit.
The resistance is determined by the combination of the thickness of the layers and the pattern in which they are arranged. This arrangement of layers is known as the “grid” pattern. The number of layers used determines the total resistance of the resistor. By controlling the thickness and arrangement of the layers, precision resistors with specific resistance values can be manufactured.
The RER45F4990PCSL chassis mount resistors offer several advantages. These include low EMI, low noise, and the ability to dissipate more heat than standard resistors. Additionally, these resistors are resistant to vibration, impact, and shock, which makes them suitable for high G-force environments.
In conclusion, the RER45F4990PCSL chassis mount resistor is a high performing device ideal for applications requiring high electrical performance, heat resistance, and overload protection. It is used in a variety of applications such as automotive, industrial, and solar solar systems, and is based on thick film technology which enables precise resistance values to be manufactured. These resistors offer numerous advantages, ranging from low EMI and noise, to the ability to dissipate more heat than standard resistors.
