GS4B027871FFT

GS4B027871FFT Description

The GS4B027871FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. This thin-film resistor network offers a 7.87KΩ resistance per element with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in precision circuits. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable operation across a wide thermal range. The 0.05W (1/20) power rating per resistor and 100V maximum voltage rating provide reliable performance in low-power, high-voltage environments.

GS4B027871FFT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm × 5.99mm × 1.45mm) with gull-wing terminals for secure surface mounting.
• Bussed Network Design: Simplifies PCB layout by connecting resistors in a shared bus configuration (Circuit Designator: BUS).
• High Precision: ±1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive (non-PPAP) environments.
• Thin-Film Technology: Delivers superior stability and low noise compared to thick-film alternatives.
