Additional Details

The '1472' in the part number likely represents a resistance value of 14.7 kΩ (kiloohms), with the '2' often indicating a tolerance of 0.1% or 0.01% – datasheets are needed to confirm this. The '-03-' section of the part number may refer to the temperature coefficient. Thin film resistors are manufactured by depositing a thin layer of resistive material onto a ceramic substrate. They are known for their superior performance compared to thick film resistors. Key specifications include resistance tolerance, TCR (temperature coefficient of resistance), power rating (typically low for 0402 size), and voltage rating. It is important to consult the manufacturer's datasheet for complete electrical and mechanical specifications to ensure proper application and performance within the circuit. Operating temperature ranges are usually within -55°C to +125°C.
