GS4A0254R9DT Description

The GS4A0254R9DT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 54.9Ω resistance with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, this ceramic-based thin-film resistor network ensures stable performance across a wide temperature range (70°C to 125°C). Its isolated circuit design (ISOL) allows independent resistor operation, making it ideal for precision voltage division or signal conditioning. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, it balances compactness (4.9mm × 5.99mm × 1.45mm) with reliability in harsh environments.
