GUS-QS0B-03-2550-GD Description

The GUS-QS0B-03-2550-GD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device features 19 resistors, each with a 255 Ohm resistance value and a tight 2% tolerance. The network operates within a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 1W (0.05W per resistor). Its ±25ppm/°C temperature coefficient ensures stable performance under thermal stress, while the 100V maximum voltage rating makes it suitable for moderate-voltage circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, with a compact footprint of 8.66mm (L) × 6.02mm (D) × 1.47mm (H). Packaged in a tube, this non-automotive and non-PPAP compliant component is ideal for industrial and commercial electronics.

GUS-QS0B-03-2550-GD Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• High-Density Integration: 19 resistors in a compact QSOP package save board space versus discrete solutions.
• Robust Thermal Performance: Operates up to 125°C with derated power handling at elevated temperatures.
• Low TCR (±25ppm/°C): Minimizes resistance drift across temperature variations.
• Gull-Wing SMD Termination: Ensures reliable solder joints and compatibility with automated assembly.
• Non-Compliant with EU RoHS: Suitable for legacy or exempted applications requiring leaded finishes.
