GS4A011202BBT Description

The GS4A011202BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 12 kΩ resistance and an exceptional ±0.1% absolute tolerance. Its ±100 ppm/°C temperature coefficient ensures minimal resistance drift across the 70°C to 125°C operating range, making it ideal for precision analog and digital circuits. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations offers robust surface-mount compatibility, while the ceramic construction enhances thermal and mechanical reliability. Rated for 100 V maximum voltage and 0.4 W total power dissipation, it balances compactness with performance.
