GS4A028250BBT Description

The GS4A028250BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 825Ω and an absolute tolerance of ±0.1%. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient (±50ppm/°C), ensuring minimal resistance drift. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and signal conditioning circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.
