Chassis Mount Resistors

Resistors are electronic components that can be used for a wide variety of applications, from measuring circuit simplicity to providing electrical power. Chassis mount resistors, such as the RER65F2870RCSL from Arcol, are low-power resistors designed for easy installation in any printed circuit board or housing. This type of resistor is known for its robust construction and wide temperature range, making it suitable for applications where the device must withstand extreme temperatures.

Application Field

The RER65F2870RCSL is capable of providing power to nearby circuits or components, and is well-suited to resistive load switching and bypass operations. This device is commonly used in a variety of power, temperature control, and temperature sensing applications, such as: electric motors, industrial and office appliances, lighting, instrumentation, and automotive systems. Due to its superior thermal and mechanical properties, the RER65F2870RCSL is also a popular choice for general-purpose circuitry that requires higher resistance values. The device is especially well-suited for high-frequency circuits and audio-amplifiers, where it can handle sudden changes in load conditions without oversaturating.

Working Principle

The working principle of the RER65F2870RCSL involves two main components: a heating element that is embedded within the device and a heatsink, which is mounted externally and circulates air to cool the device.To operate, the heating element is connected to an electrical power source and the heatsink is mounted to the chassis outside of the device. As the heat generated by the heater is absorbed by the heatsink, the temperature of the device increases, causing the resistance of the device to decrease. As the temperature rises, the resistance gets lower, allowing more current to flow through the circuit.The RER65F2870RCSL is designed to provide steady and reliable performance over its operating range. By controlling the amount of heat generated, the device can be operated in a wide temperature range, without introducing any significant heat into the surrounding environment.

Conclusion

The RER65F2870RCSL is a robust and reliable chassis mount resistor that is perfect for a variety of low-power applications. The device offers a wide temperature range and superior thermal and mechanical properties, making it suitable for high-frequency and audio-amplifier circuits. Furthermore, the device is compact and easy to install, making it an ideal solution for many applications.
