GS4A021053GFT Description

The GS4A021053GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Packaged in an 8-pin narrow SOIC (SOIC-C) with isolated elements, it features four 105 kΩ thin-film resistors with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in differential signal processing. The device operates within a wide temperature range of -70°C to +125°C, derated at elevated temperatures, and offers a low temperature coefficient of ±50 ppm/°C for minimal resistance drift. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for moderate-power circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal stability and durability.
