GS4A021401CT

GS4A021401CT Description

The GS4A021401CT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding applications requiring tight tolerance and stability. Housed in an 8-pin narrow SOIC ceramic package, it features 1.4 kΩ thin-film resistors with an absolute tolerance of ±0.25% and a low ±50 ppm/°C temperature coefficient. The device operates over a wide temperature range (-70°C to +125°C) and delivers a derated power rating of 0.1W per resistor (0.4W total). Its 100V maximum voltage rating, gull-wing termination, and surface-mount design make it suitable for automated assembly processes. The ceramic case ensures superior thermal performance and durability in harsh environments.
