GS4A013090BT

GS4A013090BT Description

The GS4A013090BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 309Ω resistance and an exceptional ±0.1% tolerance. Encased in a robust rectangular ceramic SOIC package, it offers superior thermal stability with a ±100ppm/°C temperature coefficient and operates reliably across a wide temperature range of -70°C to +125°C. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact, surface-mount designs.
