GS4B031003DDT Description

The GS4B031003DDT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for BUS circuit applications. Encased in a ceramic SOIC-8 package, it offers a 100KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic substrate enhances thermal performance and durability.

GS4B031003DDT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength vs. plastic alternatives.
• High-Density Integration: 7 resistors in a compact 4.9mm x 5.99mm footprint (SOIC-8), saving PCB space.
• Wide Temperature Range: Reliable performance from -70°C to +125°C, even at derated power.
• Automation-Friendly: Gull-wing leads with 1.27mm pitch ensure compatibility with pick-and-place systems.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation where PPAP compliance isn’t required.
