GS4A011100GT

GS4A011100GT Description

The GS4A011100GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 4-resistor isolated network features a 110Ω resistance per element with a tight ±2% absolute tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of 70°C to 125°C. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for easy surface-mount assembly. The thin-film technology provides excellent stability and low noise, while the ceramic case ensures durability and heat dissipation. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for high-density PCB designs.

GS4A011100GT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Precision: ±2% tolerance and ±100ppm/°C TCR ensure consistent performance in varying environments.
