GS4A021103JFT Description

The GS4A021103JFT 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 rated at 110KΩ with a ±5% absolute tolerance and an impressive ±50ppm/°C temperature coefficient. The device operates within a wide temperature range of 70°C to 125°C and delivers a total power rating of 0.4W (0.1W per resistor). Its SOIC-C series construction ensures robust performance in surface-mount applications, with a compact footprint of 4.9mm (L) × 5.99mm (D) × 1.45mm (H) and tight tolerances (±0.1mm height/length, ±0.2mm depth).
