GS4B0191R0GGT Description

The GS4B0191R0GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film technology. With a 91Ω resistance value and ±2% absolute tolerance, this ceramic-based network ensures reliable performance across a -70°C to +125°C temperature range. Its ±100ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for demanding environments. The 0.05W (1/20) power rating per resistor and 0.4W total power dissipation balance compactness with robustness, while the gull-wing termination facilitates easy surface mounting.

GS4B0191R0GGT Features

• Ceramic substrate for enhanced thermal stability and durability.
• Thin-film technology ensures low noise and high precision.
• Bussed (BUS) configuration simplifies circuit design by connecting resistors in a common node.
• Narrow SOIC (5.99mm × 4.9mm × 1.45mm) footprint saves PCB space.
• ±0.1mm length/height tolerances and ±0.2mm depth tolerance for consistent manufacturability.
• Non-automotive (PPAP: No) but ideal for industrial and telecom applications.
• Non-RoHS compliant, catering to legacy or specialized systems.

GS4B0191R0GGT Applications

This resistor network excels in:
