GQ8A011540DT Description

The GQ8A011540DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 154Ω resistance value per element with an ultra-tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a ceramic QSOP package with 16 gull-wing terminals, it offers excellent thermal stability and mechanical durability. The isolated (ISOL) circuit design ensures minimal crosstalk, making it ideal for precision analog and mixed-signal circuits. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with compact surface-mount (SMD) dimensions (4.9mm × 6.02mm × 1.47mm).
