GS4A033830FBT

GS4A033830FBT Description

The GS4A033830FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 383Ω and a tight ±1% absolute tolerance (with ±0.1% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range (70°C to 125°C), while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing termination ensures reliable surface-mount assembly.

GS4A033830FBT Features

• High Precision: ±1% absolute tolerance (±0.1% ratio tolerance) for accurate signal conditioning.
• Stable Performance: Thin-film technology with ±25ppm/°C TCR minimizes drift under thermal stress.
