Chassis mount resistors, specifically RER50F25R5PCSL, are components used in electrical and electronic circuits to control the flow of electricity. Generally, these kinds of resistors are used to maintain constant current or voltage within an electrical system. The RER50F25R5PCSL is an industrially-rated 50W chassis-mount resistor that is designed for the power-handling need of industrial automation. This type of resistor is capable of dissipating 25W of power and have a resistance value of 5 ohms. It also has a wide-tolerance range of ±25%, so high accuracy is achievable.
Design Features
The RER50F25R5PCSL has been designed to operate in harsher environments and temperatures ranging from -55°C to 125°C. Its component\'s body is made of anodized aluminum, which improves dissipative cooling, and offers corrosion, chemical, and vibration resistance. It also has a Coefficient of Thermal Expansion (CTE) material that compensates for thermal expansion with temperature extremes. Additionally, the resistor has an operating temperature range of -55°C to 175°C, allowing it to safely handle thermally extreme conditions.
Applications
RER50F25R5PCSL is used in high power-handling applications such as industrial automation, automotive engines, welding systems, medical imaging systems, electrical systems, power supplies, and semiconductor devices. Due to its wide operating temperature range, this resistor is also suitable for outdoor applications such as solar-powered systems, photovoltaic systems, and wind turbines. In addition, it is used in automotive applications such as for starter motors, spark plugs, and sensors.
Working Principle
RER50F25R5PCSL works according to Ohm\'s law, which states that the resistance of a resistor is equal to the ratio of voltage to current in an electrical circuit. This means that when a voltage is applied to the resistor, it will produce a certain level of current based on its resistance value. The current flow is inversely proportional to the resistance of the resistor and varies with temperature or relative humidity. The RER50F25R5PCSL is a power resistor with a resistance value of 5 ohms, which is designed to dissipate 25W of heat. This allows the resistor to control the current within an electrical circuit.
Conclusion
RER50F25R5PCSL is a chassis-mount resistor designed for power handling applications in harsh environments. It is capable of dissipating 25W of heat and has a wide temperature and resistance range, enabling it to operate in extreme environmental conditions. This type of resistor is used in various industries including automotive, medical imaging, and solar power. It is also used in electrical systems to control the current flowing through the circuit.
