GS8A028872CBT Description

The GS8A028872CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. Housed in a 16-pin SOIC ceramic package, it features 8 isolated resistors with a tight tolerance of ±0.25% and a low temperature coefficient of ±50ppm/°C, ensuring stability across a wide operating range (70°C to 125°C). Each resistor offers 88.7kΩ resistance, with a 0.1W (1/10W) power rating per resistor and a collective 0.8W total power handling. The gull-wing termination and surface-mount design facilitate automated assembly, while the 100V maximum voltage rating makes it suitable for high-voltage isolation circuits.
