GUS-QS8A-02-34R8-DD Description

The GUS-QS8A-02-34R8-DD 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 34.8Ω resistance value with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°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-density PCB designs. The isolated (ISOL) circuit design enhances signal integrity in multi-channel systems.

GUS-QS8A-02-34R8-DD Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog/digital circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained applications.
