GS8A034870FAT

GS8A034870FAT Description

The GS8A034870FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. This 16-pin narrow SOIC device features 8 isolated thin-film resistors, each with a resistance value of 487Ω and a tight ±1% absolute tolerance (with ±0.05% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures minimal resistance drift, making it ideal for precision analog and digital circuits. The SOIC package (9.91mm × 5.99mm × 1.45mm) with gull-wing terminations facilitates easy surface-mount assembly, while the ceramic case enhances thermal and mechanical stability. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it operates reliably from 70°C to 125°C with derated power.
