GS4A032100GFT

GS4A032100GFT Description

The GS4A032100GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 210Ω resistance and a tight ±2% absolute tolerance (±1% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures minimal resistance drift across the -70°C to +125°C operating range, making it suitable for environments with fluctuating thermal conditions. The SOIC-C series construction offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it combines durability with space efficiency.

GS4A032100GFT Features

• Isolated Resistor Network: Four independent resistors in an 8-pin SOIC package, eliminating crosstalk.
• Precision Thin-Film Technology: Delivers ±25ppm/°C thermal stability and 2% tolerance for consistent performance.
• Robust Ceramic Substrate: Enhances thermal management and mechanical strength vs. polymer-based networks.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Surface-Mount Design: 1.27mm terminal pitch and gull-wing leads simplify PCB integration.
• High Voltage Rating: Supports up to 100V, ideal for industrial and automotive (non-AECQ) applications.

GS4A032100GFT Applications

This resistor network excels in circuits demanding precision, isolation, and thermal resilience, such as:
