GS7B021211BT Description

The GS7B021211BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerances and stable performance. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors with a 1.21KΩ resistance value and an exceptional ±0.1% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across a wide operating range of -70°C to +125°C, making it suitable for environments with fluctuating thermal conditions. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, offering robust mechanical and electrical reliability. With a maximum voltage rating of 100V and a power rating of 0.7W (0.05W per resistor), this network balances compactness with performance.
