GQ0A013921CT Description

The GQ0A013921CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP device features 10 isolated resistors, each with a 3.92KΩ resistance, 0.25% tolerance, and ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic package, it offers superior thermal stability and durability, with a 1W total power rating (0.1W per resistor). The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating makes it suitable for high-voltage environments.
