GUS-QS8A-03-1401-FB Description

The GUS-QS8A-03-1401-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.4KΩ resistance value with a tight 1% 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 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm length, 6.02mm depth, 1.47mm height) and is supplied in tube packaging. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this component is ideal for high-reliability circuits requiring precise resistance matching and thermal stability.

GUS-QS8A-03-1401-FB Features

• Thin-film technology for superior accuracy and stability.
• Isolated circuit design (ISOL) for independent resistor functionality.
• 0.1W (1/10W) power rating per resistor, enabling balanced thermal management.
• Gull-wing termination for robust surface-mount assembly.
• Wide operating temperature range (-70°C to +125°C derated).
• Low TCR (±25ppm/°C) minimizes resistance drift under thermal stress.
• Compact QSOP package saves PCB space while supporting high-density layouts.
• Non-automotive (PPAP: No) but suitable for industrial and instrumentation use.
