GUS-QS0B-03-3012-FB Description

The GUS-QS0B-03-3012-FB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 30.1KΩ resistance value with a tight 1% 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 package with gull-wing terminations, it offers a power rating of 1W (0.05W per resistor) and a maximum voltage rating of 100V, making it suitable for high-density PCB designs. The EU RoHS non-compliant device is supplied in tube packaging, ensuring safe handling and storage.

GUS-QS0B-03-3012-FB Features

• Precision Thin Film Technology: Delivers superior accuracy (±1%) and low TCR (±25ppm/°C) for stable performance in temperature-varying environments.
• High-Density QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height, ±0.2mm depth), ideal for space-constrained designs.
• Robust Power Handling: 1W total power dissipation (0.05W per resistor) with derated performance up to 125°C.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its 125°C maximum operating temperature suits industrial and telecom applications.
• Gull-Wing Termination: Ensures reliable surface-mount soldering with a 0.64mm terminal pitch for ease of assembly.
