GS4A021130GDT Description

The GS4A021130GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 113Ω and an absolute tolerance of ±2%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for stable, low-power circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical durability.

GS4A021130GDT Features

• Isolated Resistors: Four independent 113Ω resistors with ±2% tolerance and ±0.5% ratio tolerance for precise matching.
• High-Temperature Stability: Operates up to 125°C with a ±50ppm/°C TCR, ensuring minimal drift.
• Robust Construction: Ceramic SOIC package (4.9mm x 5.99mm x 1.45mm) with ±0.1mm height tolerance for consistent mounting.
• Low-Power Efficiency: 0.1W per resistor (0.4W total) at 100V max rating, ideal for energy-sensitive designs.
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for automated assembly compatibility.

GS4A021130GDT Applications
