GS4B039102FDT Description

The GS4B039102FDT 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 91KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal stability.

GS4B039102FDT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±1% tolerance) for sensitive analog/digital circuits.
• Robust Ceramic Package: Ensures superior heat dissipation and mechanical durability compared to polymer-based networks.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down applications in multi-channel systems.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C), suitable for industrial environments.
• Compact SOIC-8 Footprint: 4.9mm × 5.99mm × 1.45mm dimensions with tight tolerances (±0.1mm height/length) save board space.
• Non-Automotive Grade: Ideal for commercial and industrial use where PPAP compliance is not required.
