GS4B021003JFT Description

The GS4B021003JFT 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 100KΩ resistance value per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in matched circuits. Its thin-film technology delivers excellent stability with a low temperature coefficient of ±50ppm/°C, making it suitable for environments with operating temperatures ranging from 70°C to 125°C. The 0.05W (1/20) power rating per resistor and 0.4W total power rating ensure reliable operation under moderate loads.

GS4B021003JFT Features

• Ceramic case for enhanced thermal and mechanical stability.
• Gull-wing termination for secure surface-mount (SMD) assembly.
• Bussed (BUS) circuit design simplifies PCB layout in voltage-divider or pull-up/pull-down networks.
• 100V maximum voltage rating and 5% tolerance for robust performance in industrial circuits.
• Compact dimensions (4.9mm x 5.99mm x 1.45mm) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Non-automotive (PPAP: No) but ideal for precision analog/digital systems.

GS4B021003JFT Applications

This resistor network excels in:

• Signal conditioning and impedance matching in communication hardware.
• Voltage division in sensor interfaces or ADC/DAC circuits.
• Pull-up/down networks for microcontrollers and FPGAs.
• Industrial control systems requiring stable, matched resistances over temperature.
• Medical devices where ceramic packaging ensures reliability in sterilized environments.
