GS4B0140R2JFT

GS4B0140R2JFT Description

The GS4B0140R2JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film technology. This ceramic-based resistor network features a 40.2Ω resistance per element with a ±5% absolute tolerance and ±100ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. Its 0.05W (1/20W) power rating per resistor and 0.4W total power dissipation make it suitable for low-power circuits, while the 100V maximum voltage rating enhances durability in high-voltage environments. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for robust surface-mount assembly.

GS4B0140R2JFT Features

• Bussed Network Design: Simplifies PCB layout by connecting resistors in a shared configuration, reducing component count.
• Thin-Film Technology: Delivers superior stability, low noise, and tight ±1% ratio tolerance for matched resistance values.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power handling at elevated temperatures.
• High Voltage Tolerance: Supports up to 100V, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Precision Gull-Wing Terminations: Ensures secure surface-mount (SMD) attachment with a 1.27mm pitch for high-density boards.
• Ceramic Substrate: Enhances thermal management and mechanical robustness compared to polymer-based networks.
