GS4A028451FT Description

The GS4A028451FT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding surface-mount applications. Encased in a ceramic SOIC package, it features 8.45KΩ thin-film resistors with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The 8-pin narrow SOIC (SOIC-C) construction offers isolated elements, making it ideal for circuits requiring independent resistor paths. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, this network balances compactness (4.9mm × 5.99mm × 1.45mm) with robustness. Its gull-wing termination and 1.27mm pitch ensure reliable PCB mounting.
