GQ8A021651DAT

GQ8A021651DAT Description

The GQ8A021651DAT 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 1.65KΩ resistance value per resistor with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability in harsh environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, making it ideal for precision analog 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) gull-wing termination.
