GQ0A0291R0GFT Description

The GQ0A0291R0GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 91Ω resistance value, 2% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers excellent thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the QSOP package (8.66mm x 6.02mm x 1.47mm) provides compact integration for space-constrained designs.
