GS4A022870GT

GS4A022870GT Description

The GS4A022870GT 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 rated at 287Ω with a ±2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal resistance drift across its operating range of 70°C to 125°C. Encased in a rectangular ceramic SOIC package, it offers superior thermal stability and mechanical durability, making it ideal for harsh environments. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network balances power handling and compactness, suited for space-constrained designs.

GS4A022870GT Features

• Isolated Resistors: Four independent 287Ω resistors with 2% tolerance for precise circuit isolation.
• Stable Performance: ±50ppm/°C TCR ensures minimal resistance variation under temperature fluctuations.
• Robust Construction: Ceramic SOIC package enhances thermal dissipation and mechanical strength.
• Surface-Mount Design: Gull-wing termination and 1.27mm pitch for easy PCB integration.
• Wide Operating Range: Functions reliably from 70°C to 125°C with derated power.
• High Voltage Tolerance: 100V maximum rating per resistor for robust signal handling.

GS4A022870GT Applications
