GS4A0252R3DDT Description

The GS4A0252R3DDT 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 52.3Ω resistance and an absolute tolerance of ±0.5%. The device operates within a wide temperature range of -70°C to +125°C, maintaining stability with a low temperature coefficient of ±50ppm/°C. Its 0.1W (1/10) power rating per resistor and 100V maximum voltage rating ensure reliable performance in precision circuits. The SOIC package (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations and 1.27mm pitch facilitates easy surface-mount assembly.
