GQ0A033572DBT Description

The GQ0A033572DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 35.7KΩ resistance, 0.5% tolerance, and a ±25ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and thermal performance, while the 1W total power rating (0.1W per resistor) supports reliable operation in high-density circuits. With a 100V maximum voltage rating and surface-mount (SMD) compatibility, this network is ideal for precision analog and mixed-signal designs.

GQ0A033572DBT Features

• High Precision: 0.5% tolerance and ±25ppm/°C TCR for stable performance in temperature-variable environments.
• Robust Construction: Ceramic substrate enhances thermal dissipation and durability.
• Isolated Design: 10 resistors with independent isolation (ISOL) reduce crosstalk in sensitive circuits.
• Compact Form Factor: QSOP package (8.66mm x 6.02mm x 1.47mm) saves board space while supporting 0.64mm pitch for high-density layouts.
• Wide Operating Range: Rated for 125°C maximum temperature and 100V voltage, suitable for industrial and automotive-grade applications (though not PPAP/Automotive certified).
• Thin-Film Technology: Delivers low noise and superior long-term reliability compared to thick-film alternatives.

GQ0A033572DBT Applications
