GUS-QS0B-03-8870-DD Description

The GUS-QS0B-03-8870-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 887Ω resistance value and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in circuit designs. Rated for 1W total power dissipation (0.05W per resistor), it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments. The ±25ppm/°C temperature coefficient minimizes resistance drift, while the 100V maximum voltage rating enhances durability in high-voltage applications.

GUS-QS0B-03-8870-DD Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high linearity.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• Gull Wing Termination: Facilitates robust surface-mount assembly with a 0.64mm terminal pitch.
• High Power Handling: 1W total rating (distributed across 19 resistors) outperforms similar networks in power density.
• Extended Temperature Range: Derated operation up to 125°C ensures reliability in automotive and industrial systems (though not PPAP or Automotive certified).
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring non-compliant materials.
