GQ8A033571DT Description

The GQ8A033571DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 3.57KΩ resistance value per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range (70°C to 125°C). Housed in a ceramic QSOP-16 package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated PCB assembly, while the isolated (ISOL) circuit configuration enhances signal integrity in multi-channel systems.

GQ8A033571DT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Package: Robust construction with ±0.1mm length/height tolerances for consistent placement.
• High Power Handling: 0.75W total rating (0.1W per resistor) at 125°C derated power.
• Isolated Configuration (ISOL): Eliminates crosstalk between channels, ideal for differential signaling.
• Automation-Friendly: 0.64mm terminal pitch and 1.63mm seated height comply with modern SMD assembly standards.
• Non-Automotive/Non-PPAP: Suitable for industrial, medical, and telecom applications where PPAP compliance isn’t required.
