GS7B034992JDT Description

The GS7B034992JDT from TT Electronics/IRC is a high-performance 14-pin narrow SOIC ceramic resistor network designed for precision applications. This bussed (BUS) configuration integrates 13 thin-film resistors, each with a 49.9KΩ resistance and a ±5% absolute tolerance, ensuring consistent performance. The device operates within a wide temperature range of 70°C to 125°C and features a ±25ppm/°C temperature coefficient, making it suitable for stable, low-drift circuits. Encased in a rectangular ceramic SOIC package, it offers excellent thermal stability and durability, with a 0.7W total power rating (0.05W per resistor). Its 100V maximum voltage rating and gull-wing termination facilitate reliable surface-mount integration.

GS7B034992JDT Features

• 13-resistor network with bussed (BUS) topology for simplified circuit design.
• Thin-film technology ensures low noise and high precision (±5% tolerance, ±0.5% ratio tolerance).
• Ceramic SOIC case enhances thermal performance and mechanical robustness.
• Wide operating range: -55°C to +125°C (derated power up to 125°C).
• Low TCR (±25ppm/°C) minimizes resistance drift under temperature fluctuations.
• Compact dimensions: 8.66mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Surface-mount (SMD) compatibility with 1.27mm terminal pitch for high-density PCB layouts.
