GS4B034990DCT Description

The GS4B034990DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 499 Ω resistance value per element with a tight 0.5% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic SOIC-8 package with gull-wing terminations, it offers excellent thermal stability and mechanical durability. The device supports a maximum voltage rating of 100V and delivers a total power rating of 0.4W (0.05W per resistor), making it suitable for precision analog and digital circuits. Its surface-mount (SMD) design and 1.27mm terminal pitch facilitate compact PCB layouts.

GS4B034990DCT Features

• High Precision: Tight 0.5% tolerance and ±25 ppm/°C TCR for stable operation.
• Robust Construction: Ceramic case and thin-film technology ensure reliability in harsh environments.
• Space-Efficient: SOIC-8 package (4.9mm × 5.99mm × 1.45mm) with gull-wing leads for easy SMD assembly.
• Wide Operating Range: Rated for -70°C to +125°C, ideal for industrial and automotive (non-AECQ) applications.
• Low Power Dissipation: 0.05W per resistor (0.4W total) balances performance and energy efficiency.
