GS4A031371BBT Description

The GS4A031371BBT is a high-precision, thin-film resistor network from TT Electronics/IRC, designed for demanding isolation and signal conditioning applications. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features four isolated resistors with a tight tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C, ensuring stability across a wide operating range (70°C to 125°C). Each resistor offers a 1.37KΩ value with a derated power handling of 0.1W per resistor (0.4W total). The device supports a maximum voltage rating of 100V and employs gull-wing terminations for reliable surface-mount assembly. Its EU RoHS non-compliant status may restrict use in certain regions, but its EAR99 classification simplifies export compliance.
