GS7A011780JDT Description

The GS7A011780JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Packaged in a 14-pin narrow SOIC (SOIC-C series), this 7-resistor isolated network features a 178Ω resistance per element with an absolute tolerance of ±5% and an exceptional ratio tolerance of ±0.5%. Its thin-film technology ensures low noise and high reliability, while the ceramic case style enhances thermal dissipation and mechanical durability. Rated for 0.1W per resistor (0.7W total), it operates across a wide temperature range of -70°C to +125°C, with a ±100ppm/°C temperature coefficient for minimal drift. The 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount assembly in demanding environments.
