GUS-QS8A-03-2701-CA Description

The GUS-QS8A-03-2701-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 2.7KΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP package with gull-wing termination, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The isolated (ISOL) circuit design provides independent resistors, enhancing flexibility in circuit design.
