GS4B028871GFT Description

The GS4B028871GFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a thin-film construction on a ceramic substrate, ensuring excellent thermal stability and reliability. With a resistance value of 8.87KΩ (±2% tolerance) and a ±50ppm/°C temperature coefficient, this network delivers consistent performance across a temperature range of 70°C to 125°C. The SOIC-C series offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it is ideal for space-constrained designs requiring stable resistance ratios (±1% ratio tolerance).

GS4B028871GFT Features

• Bussed Network Design: Simplifies circuit layout with shared common connections.
• High Precision: ±2% absolute tolerance and ±1% ratio tolerance for matched resistance values.
• Robust Construction: Ceramic case and thin-film technology ensure durability and low noise.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for compatibility with automated PCB assembly.
