GS8B026490GT Description

The GS8B026490GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in a 16-pin narrow SOIC package, this bussed network integrates 15 thin-film resistors with a 649Ω resistance value and a tight ±2% tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C, making it suitable for demanding environments. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly. With a 0.8W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances compactness with reliability.
