GS8A033570CBT Description

The GS8A033570CBT from TT Electronics/IRC is a high-precision 8-resistor isolated network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC ceramic package, it features 357Ω thin-film resistors with an exceptional ±0.25% absolute tolerance and ±0.1% ratio tolerance, ensuring minimal deviation in matched resistance values. The device operates over a wide temperature range of 70°C to 125°C with a low ±25ppm/°C temperature coefficient, making it ideal for stable performance in thermally variable environments. With a 100V maximum voltage rating and 0.1W power rating per resistor, it balances precision with robustness. The gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.
