Built with metal glaze thick film technology on an alumina ceramic substrate, it offers stable and reliable performance for a wide range of electronic applications. The 1206 package provides 0.25W power rating and 200V maximum overload voltage, making it suitable for both signal-level and moderate-power circuits in consumer, industrial, and communication equipment.","working_principle":"The RM12FT1203 uses metal glaze thick film technology where a ruthenium-based resistive paste is screen-printed onto a ceramic substrate and fired at high temperature. The resulting resistive layer provides a stable 120 kOhm resistance with \u00b11% tolerance. The metal glaze structure offers good long-term stability and moisture resistance. Nickel barrier and tin terminations provide reliable solder connections while preventing leaching of the resistive element during assembly processes.","pin_description":"\n
