GS4B029091CBT Description

The GS4B029091CBT from TT Electronics/IRC is a high-precision 7-resistor thin film network in an 8-pin SOIC package, designed for surface-mount applications. It features a 9.09KΩ resistance value per resistor with an ultra-tight ±0.25% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal stability, while the 0.4W total power rating (0.05W per resistor) makes it suitable for low-power circuits. With a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is ideal for precision analog and digital systems.

GS4B029091CBT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case and gull-wing leads for durability in harsh environments.
• Compact Design: 4.9mm × 5.99mm × 1.45mm SOIC package with 1.27mm terminal pitch, saving PCB space.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Low Power Dissipation: 0.05W per resistor (0.4W total) for energy-efficient designs.
• Non-Compliant with EU RoHS, making it suitable for legacy or specialized applications.
