GS4A0378R7DT Description

The GS4A0378R7DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 78.7Ω and an absolute tolerance of ±0.5%. The device operates within a temperature range of 70°C to 125°C and offers a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, it is engineered for reliability in precision circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal dissipation.
