GQ8A037872CAT Description

The GQ8A037872CAT 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 78.7KΩ resistance value per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°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 mechanical durability, making it ideal for harsh environments. The isolated (ISOL) circuit design minimizes crosstalk, while the gull-wing termination ensures reliable surface-mount assembly.
