GS4A0297R6GCT Description

The GS4A0297R6GCT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features 97.6Ω thin-film resistors with a tight ±2% absolute tolerance and an exceptional ±0.25% ratio tolerance, ensuring superior matching accuracy. The device operates over a wide temperature range of -70°C to +125°C with a ±50ppm/°C temperature coefficient, delivering stable performance under thermal stress. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and signal conditioning circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case ensures robust mechanical and thermal properties.
