GUS-QS8A-01-4301-GB Description

The GUS-QS8A-01-4301-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.3K Ohm resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70 to 125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and is supplied in a protective tube. With a maximum voltage rating of 100V and a total power dissipation of 0.75W (3/4W), it is engineered for reliability in demanding circuits.

GUS-QS8A-01-4301-GB Features

• Thin-film technology for superior accuracy and stability.
• Isolated (ISOL) circuit design, enabling flexible routing in multi-channel systems.
• 0.1W (1/10W) power rating per resistor, ideal for distributed loads.
• Gull-wing termination for robust surface-mount assembly (SMD).
• Wide operating temperature range (-55°C to +125°C derated).
• Low TCR (±100ppm/°C) minimizes resistance drift under thermal stress.
• QSOP package with 0.64mm terminal pitch, saving PCB space.
• Non-automotive (PPAP: No) but suitable for industrial and telecom applications.
