GS4B026491FFT

GS4B026491FFT Description

The GS4B026491FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. This ceramic-based thin-film resistor network offers a 6.49KΩ 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 SOIC-C series construction provides robust mechanical integrity, while the gull-wing termination ensures reliable solderability. With a 100V maximum voltage rating and 0.4W total power dissipation, it balances compactness (4.9mm × 5.99mm × 1.45mm) with robust electrical performance.
