GUS-QS0B-03-7872-GA

GUS-QS0B-03-7872-GA Description

The GUS-QS0B-03-7872-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 78.7KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent stability across a wide operating range of -70°C to +125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for compact, high-density designs. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.

GUS-QS0B-03-7872-GA Features

• Precision Thin Film Technology: Ensures low noise and high accuracy (±25ppm/°C TCR).
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with gull-wing terminals for reliable SMT assembly.
• Robust Power Handling: 1W total dissipation (0.05W per resistor) at 125°C max operating temperature.
• BUS Circuit Designator: Optimized for bus termination and voltage division applications.
• Stable Performance: 2% tolerance and ±0.1mm height/length tolerances ensure repeatability.
• Non-RoHS Compliant: Suitable for legacy or specialized systems requiring leaded components.

GUS-QS0B-03-7872-GA Applications
