The MMU01020C1004FB300 is a 1MOhm ±1% 0.3W chip resistor MELF, 0102 anti-sulfur, automotive AEC-Q200 thin film manufactured by Vishay. This chip resistor features a resistance tolerance of ±1%, a power rating of 0.3 watts, and is an 0102 anti-sulfur, meaning it is resistant to sulfuric acid-induced corrosion. This chip is manufactured using a thin film construction, giving it tighter tolerances than wire-wound types, and is designed for use in automotive applications that meet the requirements of AEC-Q200. It is compliant with RoHS, REACH, and Conflict Minerals directives.
