GUS-QS0B-02-3402-DD Description

The GUS-QS0B-02-3402-DD 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 34K Ohm resistance value and a tight 0.5% 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, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical performance, while the gull-wing termination ensures reliable solderability in automated PCB assembly.

GUS-QS0B-02-3402-DD Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth), ideal for space-constrained designs.
• High Power Density: 1W total dissipation (distributed across 19 resistors) enables efficient heat management.
• Automation-Friendly: Gull-wing leads with 0.64mm pitch simplify pick-and-place assembly.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated power up to 125°C).
• Non-Automotive/Non-PPAP: Optimized for industrial, telecom, and instrumentation use.
