GS4A031243BT

GS4A031243BT Description

The GS4A031243BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 124KΩ resistance and an exceptional ±0.1% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, ensuring stability in fluctuating thermal conditions. Encased in a rectangular ceramic SOIC package, it offers 0.4W total power dissipation (0.1W per resistor) and a maximum voltage rating of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable surface-mount assembly, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) suit space-constrained designs.
