GUS-QS8A-02-1873-FA Description

The GUS-QS8A-02-1873-FA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 187K Ohm resistance with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C 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 a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it balances power handling and precision in demanding environments.

GUS-QS8A-02-1873-FA Features

• Thin-film technology: Delivers superior accuracy, low noise, and long-term stability.
• Isolated design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• High power density: 0.1W per resistor (0.75W total) in a compact QSOP package.
• Wide operating range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Robust construction: Gull-wing leads ensure reliable surface-mount attachment, even under thermal stress.
• Non-automotive grade: Suitable for industrial, medical, and telecom applications where PPAP compliance is not required.
