GS4A011431DAT

GS4A011431DAT Description

The GS4A011431DAT from TT Electronics/IRC is a high-precision 4-resistor network designed for demanding isolation and signal conditioning applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features isolated thin-film resistors with a 1.43KΩ resistance value and an exceptional ±0.5% absolute tolerance (±0.05% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient, ensuring stability in harsh environments. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.
