GS4A034752GT

GS4A034752GT Description

The GS4A034752GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 47.5KΩ resistance and a tight ±2% tolerance. The device operates within a wide temperature range of -70°C to +125°C, ensuring reliability in demanding environments. Its ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for circuits where thermal stability is critical. The SOIC-C series construction offers robust mechanical integrity, with a compact footprint (4.9mm x 5.99mm x 1.45mm) and gull-wing terminations for easy surface-mount assembly.

GS4A034752GT Features

• Isolated Resistors: Four independent 47.5KΩ resistors with 2% absolute tolerance, eliminating crosstalk in sensitive circuits.
• Thermal Stability: ±25ppm/°C TCR ensures minimal resistance variation across the -70°C to +125°C operating range.
• High Power Handling: 0.1W per resistor (0.4W total) with derating up to 125°C, suitable for power-dense designs.
• Robust Construction: Ceramic substrate and thin-film technology provide excellent durability and long-term reliability.
• Precision Dimensions: Tight tolerances on package dimensions (±0.1mm height/length, ±0.2mm depth) ensure consistent PCB placement.
• 100V Maximum Rating: Supports higher voltage applications compared to standard resistor networks.
