Application Field

The RER75F3481RC02 chassis mount resistor is suitable for a wide variety of applications, such as power supplies, motor drives, automotive applications, security systems, home appliances, and medical equipment. The resistor has a very low thermal EMF, which makes it suitable for applications where small signal loops require heating from thermal energy. The high-power rating and wide resistor range make it ideal for high-voltage and high-current applications. Furthermore, its reliability and durability make it suitable for long-term operations, such as those in aerospace applications.

Working Principle

The RER75F3481RC02 chassis mount resistor works on the principle of thermoelectric cooling. Thermoelectric cooling involves passing a current through a thermoelectric material, usually a semiconductor. This generates a temperature difference at the two ends of the material, which in turn creates a voltage difference. This voltage difference can then be used to drive a current through the resistor\'s internal elements, causing the resistor to heat up. The amount of resistance is determined by the voltage and current applied.

The resistor also features a built-in 36R bushing, which enables the movement of heat away from the resistor. This helps to ensure that the overheating does not become an issue and that a steady state temperature is maintained. In addition, the ceramic core and insulation sleeve help to provide electrical isolation and ensure reliable electrical connection.

Conclusion

The RER75F3481RC02 chassis mount resistor is designed to meet the requirements of rugged, high-power applications. It has a power rating of 75W and a resistance range of 1 ohm to 5 megohms. The resistor has a built-in 36R bushing to help dissipate heat, and the ceramic core and insulation sleeve provide reliable electrical connection. This makes it suitable for a variety of applications, such as power supplies, motor drives, automotive applications, and aerospace applications. The working principle of the resistor is thermoelectric cooling, which involves a temperature difference generated by a voltage difference.
