GS4A026812JT

GS4A026812JT Description

The GS4A026812JT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 68.1kΩ resistance and a ±5% tolerance. The device operates within a wide temperature range of 70°C to 125°C, with a ±50ppm/°C temperature coefficient, ensuring minimal resistance drift. Its SOIC-C series construction offers 0.1W (1/10) power rating per resistor (0.4W total), 100V maximum voltage rating, and surface-mount gull-wing termination for reliable PCB integration. The ceramic case provides excellent thermal and mechanical stability, while the rectangular package (4.9mm x 5.99mm x 1.45mm) ensures compact board space utilization.
