GUS-QS8A-03-4302-GG Description

The GUS-QS8A-03-4302-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 8-resistor isolated network features a 43K Ohm resistance value with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a broad temperature range of 70°C to 125°C (derated power). Housed in a 16-pin QSOP package with gull-wing termination, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and a 0.64mm terminal pitch, making it ideal for space-constrained designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is RoHS non-compliant and supplied in tube packaging.

GUS-QS8A-03-4302-GG Features

• Precision Thin Film Technology: Delivers low noise, high stability, and excellent TCR performance (±25ppm/°C).
• Isolated Resistor Network (ISOL): Eight independent 43K Ohm resistors with 2% tolerance for accurate signal conditioning.
• Compact QSOP Package: Space-saving 16-pin gull-wing SMD design (4.9mm × 6.02mm × 1.47mm) for high-density layouts.
• Robust Power Handling: 0.75W total dissipation (0.1W per resistor) and 100V voltage rating for demanding circuits.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power, peaking at 125°C maximum.
• Industrial-Grade Reliability: Non-automotive but suited for industrial, telecom, and instrumentation applications.
