GS4A031211BBT Description

The GS4A031211BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 1.21 kΩ and an absolute tolerance of ±0.1%. The network operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient of ±25 ppm/°C, ensuring minimal drift under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent power dissipation (0.1W per resistor, 0.4W total) and a maximum voltage rating of 100V, making it suitable for precision analog and digital circuits.

GS4A031211BBT Features

• High Precision: ±0.1% absolute tolerance and ±0.1% ratio tolerance for matched performance.
• Stable Performance: Low TCR (±25 ppm/°C) and derated power up to 125°C.
• Robust Construction: Ceramic case with gull-wing termination for reliable surface-mount assembly.
• Isolated Design: Four independent resistors in an 8-pin SOIC package (4.9mm × 5.99mm × 1.45mm).
