Additional Details

The RN412ESTTE1803F50 typically comes in a small surface-mount package (e.g., 0603, 0805, or 1206). The resistance value is 180 kOhms. It is designed to operate within a specified power rating, and exceeding this rating can lead to resistor failure. The resistor is made of a thin film resistive element deposited on a ceramic substrate. The terminals are typically made of a solderable material, such as tin or a tin alloy, to ensure good solderability. The operating temperature range is usually wide, allowing it to be used in harsh environments. This part number is part of a larger RN series, and other resistance values and tolerances are available within the same series.
