GS4A0354R9GT

GS4A0354R9GT Description

The GS4A0354R9GT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 54.9Ω resistance and a tight ±2% tolerance. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, ensuring reliability in thermally challenging environments. Its ±25ppm/°C temperature coefficient minimizes resistance drift, making it ideal for precision circuits. The SOIC-C series construction offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for robust surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it balances performance with space efficiency.
