GS4B018201CT

GS4B018201CT Description

The GS4B018201CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this bussed 7-resistor array offers a 8.2KΩ resistance with an exceptional ±0.25% absolute tolerance and a ±100ppm/°C temperature coefficient. Its thin-film technology ensures stable performance across a wide temperature range (70°C to 125°C derated, 125°C max), making it suitable for precision circuits. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, providing robust mechanical and thermal stability. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling with compact surface-mount (SMD) design (4.9mm × 5.99mm × 1.45mm).
