GS8A034870CAT

GS8A034870CAT Description

The GS8A034870CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under elevated temperatures. This 16-pin narrow SOIC package features 8 isolated thin-film resistors, each with a 487Ω resistance and an exceptional ±0.25% absolute tolerance (±0.05% ratio tolerance). The device operates within a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 0.8W (0.1W per resistor). Its ±25ppm/°C temperature coefficient ensures minimal resistance drift, while the 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount PCB designs. Encased in a rectangular ceramic SOIC package (9.91mm x 5.99mm x 1.45mm), it offers robust mechanical stability and thermal dissipation.
