GS7B011781GDT Description

The GS7B011781GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Housed in a 14-pin narrow SOIC package, this bussed network integrates 13 thin-film resistors, each with a resistance value of 1.78KΩ and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, ensuring reliability in harsh environments. Its ±100ppm/°C temperature coefficient and ±0.5% ratio tolerance make it ideal for applications requiring stable, matched resistance values. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, offering robust mechanical and thermal performance.
