GQ0A031820FCT Description

The GQ0A031820FCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 182Ω resistance value and a tight 1% tolerance, ensuring consistent performance in precision circuits. The ceramic case and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees stability across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, it suits high-density PCB designs requiring minimal drift and high isolation.
