GQ0A029091JFT Description

The GQ0A029091JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 9.09KΩ resistance value and a 5% tolerance. Encased in a ceramic package, it offers excellent thermal stability, with a ±50ppm/°C temperature coefficient and a power rating of 0.1W per resistor (1W total). The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its compact dimensions (8.66mm × 6.02mm × 1.47mm) make it ideal for space-constrained designs. Rated for 100V maximum voltage and an operating temperature range of -70°C to +125°C, this network is suited for demanding environments.
