GS8A023921CBT Description

The GS8A023921CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor network features a 3.92KΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin SOIC ceramic package, it offers 0.8W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and mixed-signal circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical reliability.
