GS4A034641GFT Description

The GS4A034641GFT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation (ISOL) applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC ceramic package, this thin-film resistor network offers a 4.64KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring exceptional accuracy in signal conditioning and voltage division. Its ±25ppm/°C temperature coefficient guarantees stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total) further enhance its reliability in precision analog and mixed-signal designs.

GS4A034641GFT Features

• Ceramic SOIC Package: Robust, rectangular ceramic case (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for secure surface mounting.
• Isolated Thin-Film Resistors: Four electrically isolated resistors with low TCR (±25ppm/°C) for minimal drift.
• High Precision: ±2% absolute tolerance and ±1% ratio tolerance for critical analog applications.
• Wide Temperature Range: Derated power operation up to 125°C, ideal for industrial and automotive-adjacent systems (though not PPAP/automotive-certified).
• 100V Voltage Rating: Supports higher-voltage circuits compared to standard networks.
• Low Profile: 1.63mm seated height with tight dimensional tolerances (±0.1mm height, ±0.2mm depth) for compact PCB layouts.
