GS4A021370GCT Description

The GS4A021370GCT 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 device features four isolated thin-film resistors, each with a resistance value of 137Ω and a tight ±2% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of -70°C to +125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations enables easy surface-mount assembly, while the ceramic case enhances thermal and mechanical durability. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network balances compactness with robust performance.

GS4A021370GCT Features

• Isolated Resistors: Four independent 137Ω resistors with ±2% tolerance and ±0.25% ratio tolerance for precision signal conditioning.
• Stable Performance: Thin-film technology and ±50ppm/°C TCR ensure reliability across a wide -70°C to +125°C range.
• Robust Construction: Ceramic SOIC package offers superior thermal dissipation and mechanical strength compared to plastic alternatives.
• High-Density Design: Compact 8-pin narrow SOIC (4.9mm x 5.99mm) with 1.27mm terminal pitch optimizes PCB space.
