GQ0A031800CT Description

The GQ0A031800CT 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 180Ω resistors with an exceptional tolerance of ±0.25% and a low temperature coefficient of ±25ppm/°C, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Encased in a robust ceramic package with gull-wing terminations, it offers superior thermal stability and mechanical durability in surface-mount designs. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), this network is ideal for precision analog circuits where minimal drift and high reliability are critical.
