GUS-QS8A-02-7870-JA Description

The GUS-QS8A-02-7870-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 787Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP (QSOP-16) package, it offers a compact 4.9mm × 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained surface-mount (SMD) designs. The gull-wing termination ensures reliable solderability, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating provide robust handling of distributed loads.

GUS-QS8A-02-7870-JA Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive circuits.
• Isolated Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• High Voltage Tolerance: Supports up to 100V, suitable for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Compact QSOP Package: 0.64mm terminal pitch and 1.63mm seated height enable high-density PCB layouts.
• Non-RoHS Compliant: May be preferred for legacy or specialized systems requiring leaded components.
