GUS-QS8A-02-33R2-FF Description

The GUS-QS8A-02-33R2-FF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. This thin-film resistor array offers a 33.2Ω resistance with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing SMD termination, it features a compact footprint (4.9mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling and miniaturization. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit design.
