GS4A011201GT

GS4A011201GT Description

The GS4A011201GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 4-resistor isolated network features a 1.2KΩ resistance per element with a tight ±2% absolute tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C derated power range. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact 4.9mm × 5.99mm footprint with 1.27mm terminal pitch, making it suitable for high-density PCB layouts. The thin-film technology and ceramic case style enhance durability and thermal stability, while the gull-wing termination facilitates robust surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (0.4W total), it is ideal for signal conditioning, voltage division, and impedance matching in demanding environments.
