Additional Details

The '1692' portion of the part number likely corresponds to a resistance value of 16.9 kΩ (kiloohms), however confirmation is needed in the datasheet. The tolerance is also key to understanding this resistor's application. Typically, precision thin film resistors offer tolerances of 0.1%, 0.01% or even better. The '-03-' likely represents the specific TCR rating. Thin film resistors are manufactured by sputtering a thin layer of resistive alloy onto a ceramic substrate. Key specifications include resistance value, tolerance, TCR, power rating (typically in the milliwatt range for 0402 size), and voltage rating. Consult the manufacturer's datasheet for detailed electrical and mechanical specifications to ensure proper application. The component is suitable for reflow soldering processes.
