GS4A0391R0JDT Description

The GS4A0391R0JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 91Ω resistance value with an absolute tolerance of ±5% and an exceptional ratio tolerance of ±0.5%. Built using thin-film technology, it delivers a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift across its operating temperature range of -70°C to +125°C. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is ideal for demanding environments. Its ceramic case and gull-wing termination provide excellent mechanical and thermal stability, while the surface-mount design ensures compatibility with automated assembly processes.
