GS4B026190FT Description

The GS4B026190FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 619Ω resistance value with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic-based thin-film technology provides excellent thermal stability and reliability, while the gull-wing termination enables robust surface-mount (SMD) assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for demanding circuits requiring consistent resistance matching.

GS4B026190FT Features

• Bussed Network Design: 7 resistors connected in a bus configuration for simplified circuit layout.
• High Precision: ±1% absolute tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic substrate with thin-film technology for thermal and mechanical durability.
• Compact SOIC Package: 4.9mm × 5.99mm footprint with 1.27mm terminal pitch, suitable for high-density PCBs.
• Wide Temperature Range: Operates from -70°C to +125°C with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing leads for reliable SMT soldering.
