GS8B021181FBT Description

The GS8B021181FBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Housed in a 16-pin narrow SOIC package, this bussed (BUS) network integrates 15 thin-film resistors, each with a 1.18 kΩ resistance and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±50 ppm/°C temperature coefficient and ±0.1% ratio tolerance make it ideal for applications requiring stable, matched resistances. The SOIC-C series construction features a ceramic case, gull-wing termination, and a compact footprint (9.91 x 5.99 x 1.45 mm), suitable for high-density PCB designs.
