GS7B021270DCT

GS7B021270DCT Description

The GS7B021270DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed network integrates 13 thin-film resistors with a 127Ω resistance value and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The device operates over a wide temperature range of -70°C to +125°C, with a ±50ppm/°C temperature coefficient, making it suitable for stable performance in varying thermal conditions. Its 0.05W (1/20) power rating per resistor and 0.7W total power rating provide reliable power dissipation, while the 100V maximum voltage rating ensures robustness in high-voltage circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, adhering to SOIC package standards with precise dimensional tolerances (±0.1mm height, ±0.2mm depth).
