GUS-QS0B-02-3570-BB Description

The GUS-QS0B-02-3570-BB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 357Ω resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for compact, high-density PCB designs. Its gull-wing termination ensures reliable solder joints in automated assembly processes.

GUS-QS0B-02-3570-BB Features

• Precision Thin Film Technology: Offers low noise and high stability for critical analog circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm length/height, ±0.2mm depth).
• High Power Density: 1W total dissipation (distributed across 19 resistors) in a minimal footprint.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Automated Assembly Friendly: Gull-wing leads and 0.64mm terminal pitch simplify SMT placement.
• Non-Automotive/Non-PPAP: Ideal for industrial, medical, and test equipment where PPAP compliance is not required.
