GS4A019102BT Description

The GS4A019102BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 91kΩ resistance with an ultra-tight ±0.1% tolerance and a ±100ppm/°C temperature coefficient, ensuring minimal drift. Its thin-film technology and ceramic case provide superior thermal management, supporting operation up to 125°C with derated power handling from 70°C to 125°C. The SOIC-C series construction offers 0.4W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits.

GS4A019102BT Features

• High Precision: ±0.1% absolute tolerance for critical signal conditioning.
• Robust Construction: Ceramic substrate ensures thermal stability and mechanical durability.
• Isolated Elements: Independent resistors (non-bussed) for flexible circuit design.
• Wide Operating Range: -55°C to +125°C (full power up to 70°C).
• Low TCR: ±100ppm/°C minimizes resistance drift.
• Surface-Mount Gull Wing Terminals: 1.27mm pitch for compatibility with automated assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
