GS4B0276R8GGT Description

The GS4B0276R8GGT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for space-constrained surface-mount applications. Featuring a 76.8Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance, this ceramic-based thin-film network delivers stable performance across a -70°C to +125°C operating range. Its ±50ppm/°C temperature coefficient ensures minimal drift under thermal stress, while the 100V maximum voltage rating and 0.4W total power dissipation (0.05W per resistor) make it suitable for demanding circuits. The gull-wing termination and 1.27mm pitch facilitate reliable PCB assembly.

GS4B0276R8GGT Features

• Ceramic substrate for superior thermal stability and durability.
• Bussed topology (BUS) simplifies circuit design by interconnecting resistors.
• Thin-film technology ensures low noise and high accuracy (±2% tolerance).
• Compact SOIC package (4.9mm × 5.99mm × 1.45mm) optimizes board space.
• Wide temperature range (-70°C to +125°C) with derated power up to 125°C.
• RoHS non-compliant (contains lead), ideal for legacy or industrial systems.
• Low TCR (±50ppm/°C) minimizes resistance variation in fluctuating environments.

GS4B0276R8GGT Applications

• Voltage dividers & pull-up/down networks in precision analog circuits.
• Signal conditioning for sensors, ADCs, and DACs in industrial controls.
• Bus termination in communication interfaces (e.g., SPI, I²C).
• Power supply feedback loops requiring stable resistance ratios.
• Automotive/industrial electronics (non-automotive grade but robust for harsh conditions).
