GQ8A024220BAT Description

The GQ8A024220BAT 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 422Ω resistance value per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. 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 channels, making it ideal for precision analog and digital systems. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling with compact 4.9mm x 6.02mm x 1.47mm dimensions.
