GS4A0368R0DDT Description

The GS4A0368R0DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 68Ω resistance and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. With a temperature coefficient of ±25ppm/°C, it delivers stable performance across a wide operating range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, while the gull-wing termination facilitates reliable PCB mounting. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it combines robustness with precision.
