GS4A021021GAT Description

The GS4A021021GAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.02 kΩ resistance and a tight ±2% absolute tolerance. Its ±50 ppm/°C temperature coefficient ensures stability across a wide operating range of 70°C to 125°C, making it suitable for demanding environments. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations offers reliable surface-mount compatibility, while the 0.4 W total power rating (0.1 W per resistor) balances performance and compactness.

GS4A021021GAT Features

• Isolated Circuit Design: Four independent resistors (ISOL configuration) minimize crosstalk.
• Precision Thin-Film Technology: Delivers ±0.05% ratio tolerance for matched resistance pairs.
• Robust Construction: Ceramic case enhances thermal and mechanical durability.
• Wide Voltage Range: Supports up to 100 V maximum rating.
