Additional Details:

The RC12066FR-072KL has a maximum operating voltage that should not be exceeded. The 'FR' in the part number often indicates that it is flame retardant. It is important to consider the power dissipation requirements of the circuit to ensure the resistor is operating within its rated power. These resistors are commonly used in pick-and-place assembly processes due to their standard dimensions and flat surface. The operating temperature range is typically -55°C to +155°C, making it suitable for a wide range of environments.
