GS8A012742BBT Description

The GS8A012742BBT from TT Electronics/IRC is a high-precision 8-resistor network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin narrow SOIC (SOIC-C) ceramic package, it features isolated thin-film resistors with a tight ±0.1% absolute tolerance and ±0.1% ratio tolerance, ensuring exceptional accuracy. Each resistor offers a 27.4kΩ value with a ±100ppm/°C temperature coefficient, maintaining stability across a 70°C to 125°C derated power range. The device supports 100V maximum voltage and delivers 0.1W (1/10W) per resistor (0.8W total), making it suitable for precision analog circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS8A012742BBT Features

• High Precision: ±0.1% tolerance for both absolute and ratio values.
