GUS-QS8A-03-7321-DB Description

The GUS-QS8A-03-7321-DB from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull-wing terminations, this device offers a 7.32KΩ resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits requiring isolation (denoted by the ISOL circuit designator). The non-automotive, non-PPAP compliant part is supplied in tubes, featuring a rectangular, thin-film construction with precise mechanical tolerances (±0.1mm height, ±0.2mm depth).

GUS-QS8A-03-7321-DB Features

• High Precision: ±0.5% tolerance and ±25ppm/°C TCR for stable performance in precision analog/digital circuits.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) derated up to 125°C.
• Compact QSOP Package: 4.9mm × 6.02mm footprint with 1.47mm profile, ideal for space-constrained PCBs.
• Thin-Film Technology: Delivers low noise and superior stability vs. thick-film alternatives.
