GS4B012940GT

GS4B012940GT Description

The GS4B012940GT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for precision applications, it features a 294Ω resistance per element with a tight ±2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The thin-film technology delivers superior accuracy and reliability, while the 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits. Its 100V maximum voltage rating and gull-wing termination enable robust surface-mount integration in compact designs.

GS4B012940GT Features

• Ceramic SOIC-C Package: Enhances thermal stability and mechanical durability.
• Bussed Network Design: Simplifies circuit layout with shared common terminals (BUS).
• Precision Thin Film: Offers low TCR (±100ppm/°C) and ±2% tolerance for critical applications.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, even at derated power.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its robustness suits industrial and telecom applications.
