GS4B033901FFT

GS4B033901FFT Description

The GS4B033901FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 3.9KΩ resistance value with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in critical circuits. The thin-film technology delivers a low ±25ppm/°C temperature coefficient, making it ideal for environments with temperature fluctuations (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling and compactness (4.9mm × 5.99mm × 1.45mm). The gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB integration.
