Chassis mount resistors are a type of component used to regulate the flow of electricity in a circuit. They are designed to be mounted to the chassis of an electronic device, providing shielding from corrosion and physical damage, as well as acting as a reliable regulator of current. The RER70FR649RC02 is an example of one such component, utilised in a variety of applications.
RER70FR649RC02 resistors are used in high-frequency switching circuits, providing sufficient current reflow whilst maintaining high voltage. Their ability to withstand high temperatures, rated at up to 175°C, makes them highly reliable over long periods of time. At the same time, their compact size makes them ideal for limited space applications, such as mobile phones and other devices where board space is at a premium.
The RER70FR649RC02 works by providing a barrier between two electrical components to limit the current flow. This is done through the carbon compound which is embedded within the resistor; when current runs through the device, the compound temperature rises in proportion to the amount of current flowing through the device. This creates a voltage-dependent resistance which is equal to the current flow, effectively regulating the power through the circuit.
This resistor is also designed to perform in conditions with high levels of electromagnetic interference, often caused by high voltage. This is due to the metal casing which shields the resistor from these disturbances, reducing their effect on the overall performance. Furthermore, the RER70FR649RC02 also features an eyelet design, allowing for easy cable management and flexible placement. This makes it an excellent choice for applications in tight spaces, such as handheld devices or automotive electronics, in which controls are decentralized.
RER70FR649RC02 resistors are widely used in both professional and consumer electronic devices, due to their combination of small size, high voltage capability, and high temperature resistance. The shielding of incoming current and interference makes it reliable in a range of environments, whilst the eyelet design allows for dynamic placement to optimise the use of space. As such, this type of chassis mount resistor is the ideal choice for the digital world.
