GS8B034990GBT Description

The GS8B034990GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 16-pin narrow SOIC (SOIC-C series) device integrates 15 bussed resistors with a 499Ω resistance value and a tight ±2% absolute tolerance, ensuring reliable signal conditioning and voltage division. Its thin-film technology delivers excellent stability with a low ±25ppm/°C temperature coefficient, making it suitable for environments with fluctuating thermal conditions. The 0.05W (1/20) power rating per resistor and 0.8W total power rating enable efficient operation in compact circuits. With a 100V maximum voltage rating and 125°C maximum operating temperature, this network is engineered for durability in demanding electronic systems.

GS8B034990GBT Features

• Ceramic substrate for enhanced thermal and mechanical stability.
• Bussed (BUS) circuit design simplifies routing in multi-resistor applications.
• Gull-wing termination ensures reliable surface-mount (SMD) connections.
• Precision thin-film resistors with ±0.1% ratio tolerance for matched performance.
• SOIC package (9.91mm × 5.99mm × 1.45mm) with ±0.1mm length/height tolerances for consistent PCB assembly.
• Wide temperature range (70°C to 125°C derated) for industrial and automotive-adjacent use (non-automotive PPAP).
• Non-RoHS compliant (suitable for legacy or exempt applications).
