GS4A031211GAT Description

The GS4A031211GAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 4-resistor isolated network features a 1.21KΩ resistance value with a tight ±2% absolute tolerance and an exceptional ±0.05% ratio tolerance, ensuring reliable performance in precision circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package with gull-wing termination, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient. The thin-film technology enhances accuracy and durability, while the ceramic case style provides superior heat dissipation. Rated for 0.1W per resistor (0.4W total) and operating within a 70°C to 125°C derated power range, it supports voltages up to 100V.
