GUS-QS0B-02-1001-CA Description

The GUS-QS0B-02-1001-CA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a compact 20-pin QSOP package with gull-wing terminations, offering a 1KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a -55°C to +125°C range, with derated performance up to 125°C. Its 100V maximum voltage rating and thin-film technology ensure stability in precision analog and digital circuits.

GUS-QS0B-02-1001-CA Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for critical signal conditioning.
• Robust Construction: Thin-film technology provides low noise and long-term stability.
• Space-Efficient: Compact 8.66mm × 6.02mm × 1.47mm QSOP package (±0.1mm dimensional tolerances).
• Automated Assembly Friendly: Gull-wing terminations and 0.64mm pitch enable reliable SMT placement.
• Wide Operating Range: Suitable for industrial environments (-55°C to +125°C).
• Non-Automotive/Non-PPAP: Ideal for commercial and industrial applications without automotive compliance requirements.

GUS-QS0B-02-1001-CA Applications
