GS4A0276R8GT

GS4A0276R8GT Description

The GS4A0276R8GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 4-resistor isolated network features a 76.8Ω resistance value with a tight ±2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. The thin-film technology provides superior accuracy and low noise, while the 100V maximum voltage rating and 0.1W power rating per resistor make it suitable for high-density PCB designs.
