GS4A012051DAT Description

The GS4A012051DAT 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 2.05KΩ thin-film resistors with an absolute tolerance of ±0.5% and an exceptional ratio tolerance of ±0.05%, ensuring superior matching accuracy. With a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and signal conditioning circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
