GS7B027500BBT Description

The GS7B027500BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors, each with a 750Ω resistance and an absolute tolerance of ±0.1%. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in harsh environments. Its ±50ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.7W total) make it suitable for precision analog and digital circuits. The SOIC-C series construction features gull-wing terminations for surface-mount assembly, with a compact footprint of 8.66mm × 5.99mm × 1.45mm and tight dimensional tolerances (±0.1mm height/length, ±0.2mm depth).
