GUS-QS8B-01-1802-GF Description

The GUS-QS8B-01-1802-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors, each with a 18K Ohm resistance value and a tight 2% tolerance, ensuring consistent performance across a wide temperature range of 70°C to 125°C. With a power rating of 0.75W (3/4W) and a ±100ppm/°C temperature coefficient, this network delivers stable operation in environments requiring low drift and high reliability. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for both analog and digital signal conditioning.

GUS-QS8B-01-1802-GF Features

• High-Density Integration: 15 resistors in a compact 4.9mm x 6.02mm x 1.47mm QSOP package, ideal for space-constrained designs.
• Precision Thin-Film Technology: Delivers low noise, high stability, and ±100ppm/°C TCR for critical applications.
• Robust Power Handling: 0.05W per resistor (0.75W total) with derated performance up to 125°C.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its wide temperature range and 100V rating make it suitable for industrial and telecom systems.
• Mechanical Precision: Tight tolerances on dimensions (±0.1mm height, ±0.2mm depth) ensure consistent PCB mounting.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GUS-QS8B-01-1802-GF Applications
