GS4B029100JFT Description

The GS4B029100JFT 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 910Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%. The device employs thin-film technology on a ceramic substrate, ensuring stable performance across a wide temperature range (70°C to 125°C). With a ±50ppm/°C temperature coefficient, it delivers excellent thermal stability, while its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4B029100JFT Features

• Ceramic case (SOIC package) for robust thermal and mechanical performance.
• Bussed network topology simplifies circuit design in voltage-divider or pull-up/down applications.
• Thin-film technology ensures low noise and high precision (±5% tolerance, ±1% ratio tolerance).
• Wide operating range: -70°C to +125°C with derated power up to 125°C.
• Low TCR (±50ppm/°C) for minimal resistance drift under temperature fluctuations.
• Compact dimensions (4.9mm x 5.99mm x 1.45mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Gull-wing leads (1.27mm pitch) for reliable surface-mount assembly.

GS4B029100JFT Applications
