GS4B031912GDT Description

The GS4B031912GDT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 19.1KΩ resistance value with a tight ±2% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in differential signal processing. The thin-film technology delivers a low ±25ppm/°C temperature coefficient, making it ideal for environments with operating temperatures up to 125°C. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling and compactness (4.9mm × 5.99mm × 1.45mm).

GS4B031912GDT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (SOIC) with gull-wing terminals for reliable SMT assembly.
• Bussed Network Design: Simplifies PCB layout by connecting resistors in a shared-bus configuration.
• High Precision: ±2% tolerance and ±25ppm/°C TCR ensure stability in precision circuits.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suited for industrial environments.
• Low Power Dissipation: 0.05W per resistor (0.4W total) optimizes energy efficiency.
• Non-Automotive Grade: Not PPAP-capable, but ideal for industrial, telecom, and instrumentation applications.
