GS4A031621GAT Description

The GS4A031621GAT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features 1.62KΩ thin-film resistors with a tight ±2% absolute tolerance and exceptional ±0.05% ratio tolerance, ensuring superior matching accuracy. The device operates over a wide temperature range (70°C to 125°C) with a low ±25ppm/°C temperature coefficient, making it ideal for stable performance in varying environmental conditions. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) cater to moderate-power circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.
