GUS-QS8A-03-1153-FB Description

The GUS-QS8A-03-1153-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 115K Ohm resistance value with a tight 1% tolerance and a low ±25ppm/°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 x 6.02mm footprint with a 1.47mm profile, making it ideal for space-constrained designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch facilitates high-density PCB layouts. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this network balances power handling with precision.

GUS-QS8A-03-1153-FB Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable performance in varying thermal conditions.
• Isolated Resistor Network (ISOL): Each of the 8 resistors is electrically isolated, providing design flexibility in signal conditioning and voltage division.
• Compact QSOP Package: 4.9mm length, 6.02mm depth, and 1.47mm height enable high-density PCB integration.
• Robust Power Handling: 0.1W per resistor (0.75W total) supports demanding analog and mixed-signal circuits.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Gull-Wing SMD Termination: Ensures reliable soldering and mechanical stability in automated assembly processes.
