GUS-QS0B-03-1272-GB Description

The GUS-QS0B-03-1272-GB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 12.7KΩ resistance value with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP (QSOP) package, it offers a 1W total power rating (0.05W per resistor) and supports a maximum voltage rating of 100V. Its gull-wing termination ensures reliable solderability in automated PCB assembly processes.

GUS-QS0B-03-1272-GB Features

• Precision Thin-Film Technology: Delivers superior accuracy (±2%) and low TCR (±25ppm/°C) for stable performance in precision circuits.
• Compact & Robust Design: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) suit space-constrained PCBs.
• High Power Handling: 1W total power dissipation (0.05W per resistor) supports energy-efficient designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C, ideal for industrial and automotive environments (though not PPAP/Automotive certified).
• Surface-Mount Gull Wing Terminals: Ensures strong solder joints and compatibility with high-speed pick-and-place assembly.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.
