GQ0A011540FFT

GQ0A011540FFT Description

The GQ0A011540FFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 10-resistor array features an isolated (ISOL) circuit design, with each resistor offering a 154 Ω resistance at a tight 1% tolerance. Encased in a ceramic QSOP package, it delivers 1W total power dissipation (0.1W per resistor) and operates across a wide temperature range of 70°C to 125°C. The device employs gull-wing terminations for reliable surface-mount (SMD) assembly, with a compact footprint of 8.66mm x 6.02mm x 1.47mm and a ±100ppm/°C temperature coefficient. Its 100V maximum voltage rating and non-automotive (PPAP: No) compliance make it ideal for industrial and telecom applications.
