GS8B012800CT Description

The GS8B012800CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in a 16-pin narrow SOIC (SOIC-C series), this bussed (BUS) configuration integrates 15 thin-film resistors, each with a 280Ω resistance and an ultra-tight ±0.25% tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The 0.05W (1/20) power rating per resistor and 0.8W total power dissipation balance performance with compactness, while the gull-wing termination facilitates robust surface-mount (SMD) assembly.

GS8B012800CT Features

• High Precision: ±0.25% absolute tolerance and ±100ppm/°C TCR ensure stable performance in precision applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal stability and low noise.
• Space-Efficient: Compact SOIC package (9.91mm × 5.99mm × 1.45mm) with 1.27mm terminal pitch optimizes PCB real estate.
• Bussed Design: Simplifies circuit layout by connecting multiple resistors to a common node, ideal for bus termination or pull-up/down networks.
• Wide Operating Range: Supports -70°C to +125°C, with derated power up to 125°C, outperforming standard commercial-grade networks.
