Chassis Mount Resistors encompass various types of resistors designed to protect electronic circuits from voltage spikes. The RER40F1331RC02 is a particular type of chassis mount resistor developed to provide reliable overvoltage protection in applications demanding a high level of signal integrity.

With its compact design, the RER40F1331RC02 is ideal for high speed workstations, automotive applications, and data switches. The resistor is capable of dissipating up to 1,330mW of power, making it suitable for high-power applications. It features an integral construction with a steel mount, making it resistant to shock and vibration, and offering reliable and repeatable performance.

Application Field:

The RER40F1331RC02 is suitable for applications that demand high signal integrity, such as PC motherboards, industrial automation, automotive ECUs, and high-speed network switches. This resistor is also able to protect SIM card authentication mainboards from voltage spikes, making it a great choice for SIM card authentication.

Working Principle:

The working principle of the RER40F1331RC02 is based on the principle of Faraday’s law of induction, which states that any change in the magnetic flux in a circuit will induce an emf (electromotive force) in the circuit. In this case, the resistor is exposed to rapid changes in voltage, which induces a counter-electromotive force in the circuit, thus limiting the current flow.

The RER40F1331RC02 comprises of a series wound resistor core, with an epoxy coating for protection. The core is connected to the source and the ground, in order to form a negative voltage to protect against overvoltage. This limits the maximum voltage that can flow through the resistor, thus protecting the underlying components.

Another important feature of the RER40F1331RC02 is its high pulse life. It can withstand up to dozens of volts penalty for up to 1,000 seconds, without compromising on output voltage. This makes it ideal for applications that require long-term stability.

In summary, the RER40F1331RC02 is a reliable chassis mount resistor designed to protect electronic circuits from voltage spikes and achieve a high level of signal integrity. The resistor is resistant to shock and vibration, and is suitable for high-power applications such as PC motherboards, industrial automation, automotive ECUs, SIM card authentication mainboards, and more.
