GS4A032872BBT Description

The GS4A032872BBT 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 28.7KΩ resistance and an exceptional ±0.1% absolute tolerance. The network operates over a wide temperature range of -70°C to +125°C, with a ±25ppm/°C temperature coefficient, ensuring stability in fluctuating environments. Encased in a rectangular SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it combines precision with robustness.
