GS4B012490JGT Description

The GS4B012490JGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) package, designed for precision surface-mount applications. This ceramic-based thin-film resistor network offers a 249Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±2%, ensuring consistent performance in matched impedance circuits. Its ±100ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable operation in thermally demanding environments. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in analog and digital signal conditioning circuits.
