GUS-QS8A-03-1271-CB Description

The GUS-QS8A-03-1271-CB 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 1.27KΩ 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 terminations, 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 individual resistor independence, enhancing flexibility in circuit design.
