GS4B034991GCT Description

The GS4B034991GCT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 4.99KΩ resistance per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The device features gull-wing terminations for reliable PCB mounting and is rated for 0.4W total power dissipation (0.05W per resistor). Its 100V maximum voltage rating and thin-film technology make it suitable for precision analog and digital circuits.

GS4B034991GCT Features

• Ceramic SOIC-8 Package: Robust construction with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance).
• 7-Resistor BUS Configuration: Ideal for bus termination, pull-up/pull-down networks, and voltage division.
• High Stability: ±25ppm/°C TCR and 2% tolerance ensure minimal drift in harsh environments.
• Surface-Mount Design: Gull-wing leads (1.27mm pitch) for automated assembly compatibility.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring leaded components.
