GS7B033321DCT

GS7B033321DCT Description

The GS7B033321DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors, each with a 3.32KΩ resistance and an absolute tolerance of ±0.5%. The device operates over a wide temperature range (-70°C to +125°C) with a low temperature coefficient (±25ppm/°C), ensuring stability in harsh environments. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, meeting industry standards for compact, reliable designs.
