Chassis Mount Resistors are becoming increasingly popular in a variety of different applications, mainly due to their compact size, good performance and low cost. The RER75F1210RC02 is one such model that is designed to provide reliable and accurate low resistance measurements for use in ground fault loop installations. This model is ideal for applications requiring a higher degree of accuracy than regular film resistors.
The RER75F1210RC02 features a unique structure that ensures minimal electrical distortion while maintaining a robust design. It is designed with a three-layer boundary design in which two layers of resistance material are layered in a single shell. This construction gives the component good shock resistance and higher accuracy when measuring a wide range of resistances. Additionally, it features special conductive rubber gasket seals for better environmental protection.
The RER75F1210RC02 is also designed for installation in places where temperature control is required. Its temperature range is -40 degrees Celsius to 120 degrees Celsius. It also has a large temperature coefficient of about 50% to ensure that the resistance measurements remain stable over time. The temperature-dependent resistor also has a wide range of accuracy with the general tolerance at 0.1%.
The working principle of the RER75F1210RC02 is quite straightforward. Its two layers of resistance material are electrically linked through various electrical connections to the external circuitry. When a voltage is applied to the component, the electrical current then flows between the two layers and through the resistor. As the current passes through the resistor, the resistance of the component changes, depending on the value of the voltage supplied.
The RER75F1210RC02 is perfect for applications where precise accuracy and reliable performance are required. Its ability to withstand temperature changes and its low resistance accuracy are ideal for a variety of different measurements, such as ground fault loop installations, temperature control, and low-cost resistance measurements. This model is a great choice for engineers and technicians looking for a reliable and accurate chassis mounted resistor.
