GUS-QS8A-02-4302-JF Description

The GUS-QS8A-02-4302-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device features eight isolated 43K Ohm resistors with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. With a maximum operating temperature of 125°C and a derated power range, it delivers reliable operation in thermally challenging environments. The 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor make it suitable for distributed power dissipation. Its 100V maximum voltage rating and gull-wing termination ensure secure surface-mount (SMD) integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.
