GS4A031212FT Description

The GS4A031212FT 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 12.1KΩ thin-film resistors with a tight ±1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this component is engineered for reliability in precision circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.
